Just a note to the Rocket Player users out there. Someone was seeing an issue today where they cannot add a song to a playlist. The action just silently fails. After some troubleshooting, I figured out that Rocket Player DB was corrupted, which is odd. However, the user's log file showed that Rocket Player randomly kept getting killed, which would certainly corrupt the database. The simple lesson here is that Android task killers are not your friend. I highly suggest reading about task killers via Lifehacker....
