Napster or iTunes or other for gift?

[phillydilly]

My girlfriend wanted to get a digital music service to make some new cds. I used napster back before the huge legal issues, but haven't used a digital music service in a few years. So I'm looking for advice which is better Napster, iTunes, or something else.
Also, I don't know what the "rules" are with these sites, so it would have to be something where she could burn songs to cd.

thanks
