Bacchanal

If this should go in another section, feel free to move it and accept my apologies, but I'm just lost.

My friend came over to my house and we were listening to Dangerdoom, he wanted me to burn him a CD of it and I did. Now, I downloaded the album so all the tracks are in mp3 format. The CD plays fine in my computer, my house stereo, my car stereo and his house stereo but for some reason when you play it on his computer just sounds like shit. You can't hear words, the music is all "crackly" and I don't know what to do.

I've tried saving the files to his computer so it bypassed the CD all together in case it were scratched or something. I've tried re-downloading the CD (and others) to his computer through the same service that I use and it still sounds terrible. It sounds bad through 3 seperate media players too, so I don't think that's it. It seems to play store bought CDs fine though, which is why I'm lost as to why it hates mp3s.

Is there anything to be done simply, or is he going to have to take his computer somewhere and have it looked at? Any advice on the matter would help greatly, and be appreciated even moreso.
