I was having trouble getting a newly purchased album downloaded on my phone. I unistalled the and re-installed the app to see if it would fix the problem. It removed thousands of songs that I created into playlists on my phone. It may not seem like a big deal, but these are playlist that I use for work ( I am a ballet teacher). It will take me days to find all of the music and re create these playlists. This was a VERY stressful experience.
