There are thousands of small UI problems and bugs. To me, the biggest joke/travesty is their "algorithm" which literally builds a top20 radio station echo chamber around you the moment you dare casually play a song. Then you're imprisoned rapidly by your own choices. The autoplay decision-making is atrocious. You are guaranteed to hear a song you just played manually within 10 songs. It's so painfully dumb. You could write a better system using a random number generator.

This is literally by design. Amazon doesn't want you to search, they want you to buy what they suggest on the homepage. Spotify doesn't want you listening to what you want, they want to shove profitable songs down your throat. you know how radio in america is controlled by the labels? Same with spotify.

- Downloaded songs will randomly disappear and you'll only discover this when you try to play them without an internet connection
