I wish they had a true shuffle 😔

I wish they'd bring the 'Dislike' button back. 😔

I just want a fuckin star rating system. I want winamp but with Spotify library.

I want the same! To try to make due I made a Playlist for each star category.

There is one if you use the discovery features. Well, it's not a dislike, but I think it does the same thing, maybe?

Humans think real random isn't random 🙃

It's wild but they see patterns

The problem isn’t that their random is biased or has rules, the is that it is entirely deterministic, to the point where it will play the same exact songs, in the same exact order for days. It’s as if shuffle just activates a hidden “shuffle” playlist that only updates once a week.

I'd guess that every time user presses "shuffle" they just shuffle the playlist and never change the order afterwards. So song order is really not random it's shuffled

You and I might be talking about different things.

I mean that humans don't like theoretically true random, as a cool side note

You seem upset about one implementation

Also, shuffling and having something appear near even though you throught it was shuffled is part of that finding patterns

Yep, I know what you're talking about, but spotify weights songs it thinks you'll like higher than other songs, and with big playlists it really is a noticeable problem. There are services that shuffle the order of your playlist, so then in spotify you play it with spotifys shuffle turned off, and yes there are "patterns" that I notice (one song I had in their twice, I think like a single version and album version, was right next to itself), but at least I actually hear songs I haven't heard in a long time, and I don't get the same ones regularly

Yes, that was what I was getting at. Not having true random is one thing, I understand (and like) that implementation. Apple has been doing it since the first few iPods. But Spotify “shuffle” isn’t near even, it is exactly even, as in “if you shuffle play this playlist twice two days in a row, it will play the exact same order”. Which is why people are complaining about Spotify specifically.

Why?

Because my playlist has thousands of songs yet I hear the same ones a lot, their algorithm weights songs it thinks you like to be more common in the shuffle

They built and are building a massive database of the most hard to get side of human profiles, unconscious side. Interesting to bring it to high alert of privacy warnings.

My Spotify playlist with songs I want to check out is so long that the app breaks for several minutes when I start it up with that playlist 😅
