There's only one problem I have with using spotify on my Android device. I have a premium account and I keep several playlists downloaded, it probably counts in at about 350-400 songs. So here's the problem:
I always keep spotify in offline mode and only bring it online to sync songs. But every single time I've synced everything and put it back in offline mode, the day afterwards several random songs are greyed out in every playlist. This means I have to bring spotify in online mode daily just to get the songs that disappeared back. It's very annoying.
Is there anything I can do to stop this?
