Honestly I've been using this app for a couple years now since the switch from Google play music, and honestly it's been fine up until a few days ago. A good portion of the songs in my downloads say they're unavailable and it won't finish downloading. And when I select a song from my playlist and go to my queue to shuffle my playlist with 500+ songs, it won't show me more than 25 songs now. So I can't even listen to my full playlist anymore. Very annoying especially because I pay for premium.
