If you want bugs, try Spotify app!
Does not remember now playing track correctly. End app when playing song X, start app after hour and Spotify is paused to song Y. So this doesn't remember right song.
Sometimes I get to my screen avatars where people's head and this is in every button from where I click for Queue etc. Really annoying!!! It's really random problem!
Spotify in Mobile does not also remember Repeat status. I have always Shuffle and Repet ON. But after some time it's OFF in Repeat and I'm sure I don't offed it!!! So it changes itself!
Fix or don't!
