so...
my new ride can play mp3 discs and i've heard that you can get much more music on a disc in mp3 format than the default for itunes (aac?)
anyways. i got a blank disc (80 minutes or 700 mb cd-r) and threw about 559 mb in a playlist then hit the burn button. it said it was too much one cd. would anyone be able to explain this to me. i only have very basic computer knowledge but thought that as 559 mb is less than 700 mb, it would be okay.
also, can anyone explain how i should do it to get more on a disc?
thanks...
