Motorola Droid Razr :: Music Starts Playing When Charging?

Weird glitch I noticed in the first 2-3 days post ICS. Everything seems to be normal with the phone, except for the fact that when I plug it into a charger, this will automatically trigger the device to start playing the same song. The song plays all the way through once and then ends, after which everything is normal again. While the song is playing, I can't determine which program is responsible for playing the music so that I can stop it. There is no app or icon that pops up to indicate that music is being played, it's just as if the music is being conjured out of thin air. If I try playing a track on either Google Music or My Music during this time, the second track will start playing at the same time as the first, almost as if the software doesn't recognize that another song is already playing.

Again, this only occurs when I plug the phone into a charger. Happens consistently whether it's a wall charger, usb or car charger. I've been searcing like crazy through Settings and Smart Actions to see what's causing it, but have come up empty so far. Tried rebooting a few times (both hard and soft reset), clearing out the cache....everything except a factory reset which I'd prefer to avoid if at all possible. Has anyone else experienced this issue? I've been scrolling through various message boards but haven't seen any examples of this yet.
