Been using spotify on android for 2 months now, and there has been two bugs that have been really annoying.
Sometimes when other sounds interrupt the music, the EQ randomly turns off. I have the rock preset eq as well as max bass boost because im a bass head, so the difference is really noticible when suddenly the bass levels drop a ton. Using a Galaxy S4.
Another bug is that a lot of the times when I click to play a song, it plays starts song at a really loud volume for .2 seconds or so before returning to my normal volume. Since I use headphones, this hurts my ears. Usually happens if I try to replay a song.
