it's been draining battery like crazy for me recently. I'd listen to music for an hour in the morning, and in the afternoon it'd show up as the first or second position on battery stats with "10 hours in background". it would also take its sweet time to load a playlist that I've downloaded for offline use when I was in a poor reception area, I assume because of the playlist "enhancing" or "smart shuffle", even though I've had those disabled. I've decided to temporarily move over to Deezer until I use my subscription to rip my music library, and then go back to using a local music library as the lawd intended us to do.
