    Reminds me of the old iTunes shuffle thing. When it was first introduced it was actually random but too many people complained it was broken when they heard the same artist multiple times in a row so they rewrote it as a shuffle algorithm that would feel more random than actual random.

    Just goes to show, we don’t actually want random, we want variety.

      There are two basic ways of doing “random” songs:

      1. Pick a new song randomly each time a song ends. This is the naive way to do it and can result in playing the same song twice.
      2. Randomly shuffle the list of songs once and then go through the shuffled list in order, guaranteeing that no single song gets played a second time before all songs have been played.

      The strategies are different, but I’d argue that they’re equally “random.”

      I’ve got a cheap Chinese aftermarket head unit in my car that uses strategy #1, and it’s mildly infuriating.

        Yeah, but all modern music platforms use a more advanced random, where it will avoid putting two different songs by the same artist in a row for example. But it’s still based on the second strategy you wrote.

          This seems somewhat flawed. Lets say you have 90 songs by Vengaboys, and 10 songs by Slayer in your playlist. In order to play every song without playing Vengaboys back to back, you’d need to play Slayer 4x more often than you play Vengaboys.

      Reminds me of an article I read long time ago of the need in computer games to tweak percentage chance of success and failure, because if it is true as presented 80% success rate players think it should be “almost always” and complain when one fifth of attempts fail.

        Me when the weather app says 80% chance of rain, so I go everywhere with an umbrella but it’s overcast all day long. Then it says 15% and I get rained on while walking to the store.

          I found out recently that those percentages actually mean 80% of the local AREA would have rain and 20% would not. Meaning if there is a chance of rain in your town at all it’s likely raining somewhere even if it’s just a tiny drop or two.

          So if you don’t want to get wet at all bring an umbrella if the chance is over 0%.

          Source: was talking to a meteorologist about this exact thing.

          Well rain chance is a compound probability it’s the probability that it will or will not rain multiplied by the percent of land hit with rain. Like if 50% of an area will be hit and there’s an 80% chance it will rain the number the weather Channel will give you is 40%

          In gen 1 that would be only Swift, Bide and self-targeting status moves because every 100% accuracy move can miss due to a bug (1/256). Fun fact: you would actually be able to beat the game with these 2 moves because Bide, in gen 1 only, bypasses Ghost’s immunity to Normal moves.

          ‘drop rates’ are the same thing. 10% chance doesn’t mean you will see it drop if you run a mission or defeat that boss ten times.

            Or thinking that if you didn’t get the drop in 9 attempts, you’re practically guaranteed it in the next attempt.

            Nope, still 1 in 10 chance.

            In most simple written RNG calculations, past failures do not guarantee future success.

            I believe some games will keep a tally of failures and award a successful loot after x failures to avoid frustrating players.

                Don’t use it though. The karmic dice system works for enemies too. So if you enable the system your rolls will fail less often but so will the enemy’s dice rolls. With karmic dice on I find the enemies crit me more. Especially on tactician mode.

      It’s not just about not wanting random, but randomness is actually very hard to create. Every random number is actual pseudo random

      Some basic breakdowns of this concept:

      https://slate.com/technology/2022/06/bridle-ways-of-being-excerpt-computer-randomness.html

      The problem modern computers have with randomness is that it doesn’t make mathematical sense. You can’t program a computer to produce true randomness—wherein no element has any consistent, rule-based relationship to any other element—because then it wouldn’t be random. There would always be some underlying structure to the randomness, some mathematics of its generation, which would allow you to reverse-engineer and re-create it. Ergo: not random.

        Every random number is actual pseudo random

        No, there are true random sources in a computer. Any outside input can be used to generate randomness. Mostly user input, but temperature fluctuations can work as well, if the sensor precision is high enough.

        Also the argument is only correct on a technical level for PRNGs. Choose a 65535 sided dice and make the instructions a thousand steps long and you’ll have a pretty hard time to deduce the instructions from the generated numbers. Not to mention how long the list of numbers needs to be for the attacker to start guessing.

          It is all based upon calculations with known numbers.

          A computer can’t create a number out of nothing.

          That is why Cloudflare uses lava lamps to generate random numbers for their cryptography. And even those aren’t fully random.

            No, CloudFlare doesn’t use lava lamps to generate random numbers, that was a marketing stunt. Using a camera in a completely dark room is a better source of entropy than one pointed at lava lamps.

            Also, nobody is saying that computers create a number out of nothing. The environment is a great source of entropy (temperature fluctuations, user inputs and so on) which are then expanded into a larger amount of entropy through CSPRNGs.

                All digital cameras are imperfect - there is always a bit of noise, but usually it doesn’t come through since your scene is bright enough to make small amounts of noise imperceptible. In a completely dark room the camera still tries to get data from the photo sensor, but the noise (created by temperature fluctuations, imperfections in the chip itself and so on) is all you get. You may theoretically be able to predict the noise on short time scales, but it’s a chaotic system.

        This is an irrelevant distinction for any case where you aren’t worried about someone reverse engineering the algorithm and seed by logging output. Any half decent PRNG’s output will be statistically indistinguishable from true randomness.

        I don’t use any streaming service, instead YouTube Vanced or NewPipe when I want to make a queue… But I absolutely hate that the algorithm chooses whatever it wants no matter what you play, and it’s just randomly chosen out of one of the few songs I played before. Also I sometimes play the one+ hour long compilations either to sleep (Nemo’s Dreamscapes) or fantasy music and YouTube decided that auto play will always choose one of those after playing anything (rock, metal, country, folk, name it, it doesn’t matter)

      I didn’t hear it anywhere, its personal experience. Spotify straight up isn’t shuffling any of my older liked music. Everytime I hit shuffle it always ends up localized around recently saved music and it never changes. Moreover, that’s a blogpost from a decade ago. Spotify changes stuff constantly. I seriously doubt that is the same algorithm they’re using now. ESPECIALLY considering they’ve introduced ‘Smart Shuffle’ which doesn’t only shuffle music you have saved but adds completely new music into the mix as well. That and Spotifys overall quality control has dropped drastically in the past decade.

        While I can agree with others that it might not be that strict and they may get more variety, from personal experience, my 700+ song playlist tends to focus on a handful of songs. Blue - Eiffel 65 gets a CRAZY amount of playtime for some reason. It’s a running joke with my carpool that it’s my car’s theme song. I can sometimes skip it 2-3 times on my drive to work. And some songs seem to never come up. I’ve been having some better luck with the AI DJ lately, although it will throw in an entire chunk of songs I don’t even care about as basically ads.

          Yeah I’ve got like 8000 and there have been times when it feels like it’s focusing on newly added stuff, but older stuff definitely does pop up and I feel like it’s a pretty good mix. 90% of the time I’ve just got my whole library on shuffle unless I’m actively looking for new stuff to add.

      Yeah okay, so they use the Fisher Yates algorithm. Then how the fuck in my playlist of 1000 songs am I CONSTANTLY getting hit with multiple songs by the same artist? Once in a while, okay, that’s statistically likely, but not all the time, and not every time.

        how many songs by the same artist do you have in that playlist? Your comments here don’t make sense. Repeating the same artist doesn’t make something not random and definitely doesn’t make it “the most 100 recently saved songs”. In fact repeating the same artist makes it quite likely that it is random as randomness is frequently misinterpreted as non-random if you would have read the article I linked you would understand that.

    The shuffle button does it’s thing every time you activate it. I believe, anecdotally, that it uses whatever song is playing or selected as a seed to build the random queue.

    Try this, select a song and press Shuffle. When it gets to a song you don’t want to hear, skip to a song you want to hear and toggle Shuffle off and on.

      I doubt it. True random shuffle play is rare, because humans don’t understand the chaos of true random generation, we see patterns in it and assume it’s not random.

      A truly random shuffle can play the same song twice. A truly random shuffle can play multiple songs from the same artist in a row. In the fullness of time all of these will happen with a true random shuffle.

      Nothing does that these days. Nearly everything “random” is algorithmically engineered to be less random so it feels more random to humans.

        You can definitely make a truly random shuffle that doesn’t play the same song twice within a gap of ten songs.

        You just make a list of all the song IDs that aren’t in the last ten played, and grab an item at a random index.

        Randomness is a texture not a shape. Dice are random despite only being able to present six outcomes.

          But then it is not truly random, that is the point.

          The same song 10 times in a row also has a chance of happening in a truly random list.

            Random pick without replacement is no less random than random pick with replacement. You just have a continuously smaller pool to pick from.

            It’s absolutely possible to have better randomness/shuffle without repeating songs so often.

        A truly random walk through a playlist might choose the same song twice in a row. A truly random shuffle would only have each entry appear once and you’d have to play past the end of the shuffle to hear a song repeat.

    Shuffle uses a limited list that rarely gets updated, but not just the 100 most recent ones. You can force it refresh by turning off shuffle and force closing the app.

    Hit the shuffle button twice to turn on Smart Shuffle. It will throw some brand new songs into the playlist shuffle.

        I’m on android. I just confirmed you can’t do it with an album but instead with playlists. Add a song to a playlist, hit shuffle, then hit shuffle again and a little star should appear in the shuffle icon.

          Only works on self created Playlists, not on playlists created from spotify like “Discover weekly”. The first time, you get a little popup which explains it.

    On the desktop spicetify solves this with the shuffle+ plugin. On mobile you can browse to a file in a playlist and start from there instead of shuffling the playlist. Turning off Automix also helps.

      I’ve been listening to music from the 60s almost exclusively on spotify this year. The algorithm is hell bent on me listening to the band “The Smoke”. I really don’t think a one hit wonder band that broke up in 1976 would be paying to have their music pushed so hard like that.

      I specifically use shuffle on my favourite list when I get tired of the music rut I’m in and want to listen to the shit I listened to 5-10 years ago

    Technically right. Computer can’t do actually random calculations, instead researchers have made pseudo random functions, which similarly behaves as a truly random function would.

      Yeah because that’s reasonable… give me a fuck break

      How many times you gonna sit there thumbing down tracks when listening to random? What if you actually like the song?

      This ain’t a solution
