I'm no lawyer, nor am I a copyright expert, but I am a librarian-in-training
I
think US copyright law allows the legal owner of the item (be it software, movie, music album, etc) to make a copy for backup purposes. But don't quote me

in case I've gotten in way off base...
That said, I didn't copy CD's for other people or to file sharing services for no other altruistic reason than 1) I didn't have the technology until recently and 2) after I got it, it simply never occurred to me to do so... Then I met Kasim and we talked about the reality of an artist's "share" of record sales. Sharing entire albums without compensating the artist seems like my boss asking me to work for free. Not gonna make me a happy camper...
Besides, you'd have to pry the CHSIB and QPQ discs off the CD players as well... Not bl**dy likely to happen any time soon
