I recently upgraded to Spotify premium and I wanted to download my playlists onto my phone (Samsung Galaxy S3). I manage to do this over wifi but after about 10 minutes of the playlists finishing they delete themselves. Very annoying as I have to stream them if I want to listen to them outside of my wifi and may clock up my data. I've tried a clean installation, re-syncing but nothing seems to be working! I have the latest update (0.7.1.399) NEED HELP!!!!!
