Someone mentioned that if you burn and play a mp3 CD it will play but produce no noise... Couldn't a 700MB mp3 file (or like 70 X 10MB -- you get the idea) play silence for much longer? That is about 1 min per MB of mp3 at 128 bit -- go even lower (if it'll work) and then you have a long-ass CD.
Any concern about burning up the CD motor or overheating the CD if played a lot on a long drive?
