I just picked up a 320Gig external hard drive for $80, just plug it in to the USB and move everything ya want. The 200Gig wasn't big enough anymore for the collection...lol
woah then you're pretty lucky. Your mp3's must be recorded in a lower format. 500 songs @approx 4.5 mbs each = 2,250 mb. The largest compression winrar can do is < 50%. Even in the best case scenario @ 50% you're still looking at about 1GB of songs compressed. You're going to need 2 or 3 cd's. IMO I think you could get it on 4
I still have that CD somewhere, there are a few hundred songs on there. Not sure what the qualities are, some range from only a couple megabites to 10+.
