My wife was driving and my iPad was in my messenger bag in my lap. We are pulling up to our destination and suddenly I start hearing Radiohead playing faintly. We all stop and look around. I pick up my phone and it's silent. I realize that the music is playing from my iPad. I open up my bag and pull out my iPad and it's very warm, the brightness is all the way down, and music is playing. I turned the brightness back up and went to turn the music off but it kept resuming automatically a few times until it finally quit for good. It seemed as though my iPad has never went to sleep and was running somehow even with the smart cover on... but I noticed the battery was not affected. Odd.
