A buck a song isn't bad, considering you usually pay like..20.00 for a 10 song CD, but since they're lowering the prices of CDs to 12.99, it'll be about the same value if you buy the songs online you want or not.
The good thing about purchasing songs is you can purchase only the songs you want
itunes is lookin' pretty good to me, I used emusic awhile ago but....I think it folded..didn't it?
