Bit of a random one this. After playing with m&m out of the car it played an album I bought the other day, really chuffed as most non apple players refuse to do this due to the drm. So yesterday in the car I picked another album that I bought and it crashed the m&m unit. Thought nothing much of it, so tried the same album out of the car and it played... Put it back in the car and album played fine this time. I'm not sure what the its doing, but thought I would let you guys know.
