problems downloading songs backed up on data disk

[the phoenix]

EDIT: problem solved 8)

Hi. I saved all my songs in data format on rewritable CDs.. but when I try to put it on my new computer, it says that it cannot read the source file or something.. I Googled the exact phrase and apparently lots of people have this problem.. as not all CD drives can read all types of CDs, especially when the material on them is in data format, apparently.. which is absurdly surprising as when you go to back something up you assume you'll be able to access it again lol.. so anyways I'm assuming there is some way to access the files.. maybe even something that can crack copyrighted CDs to steal the songs?.. I can't even listen to the songs though, I cannot access them at all.. do I need to hook my old computer back up and save the music?

Thanks.
