I played all cds just fine.. the format of all my cds are correct and they all worked up until the other day. I switched my cd out and put another one in and the music quickly faded out as if it didn't recognize it and wouldn't play anymore and spit the cd back out (it didn't play the ones that I haven't labeled yet which were blank on top.) Than for a random reason I put a cd in that had already been labeled along time ago and it played perfectly. I don't understand.. HELP PLEASE and thanks.
