Contraband had some sort of copy-protection that garbled the sound if you loaded it on iTunes... but there was a simple way of avoiding the copy protetction. If you give it a few weeks, I'm sure the computer geeks will post a way around it all!
I agree with Howard, if I buy the CD... I wouldn't hestitate to download the torrent if it doesn't work on iTunes.
I bought Contraband and it copied onto my iTunes without any problems. I remember hearing about this protection thing but never had a problem putting any cds onto my ipod
