I only discovered kazaa a year ago and last night used kazaa lite to listen to a few tunes i haven't heard in awhile. I also used the kazaa hack program i heard about here to make myself "1000"-I think it's actually pretty funny that anyone would think these file sharing programs wouldn't be abused but the people i know who burn music wouldn't have bought the discs to begin with.
It boils down to a matter of convienence but if i like the band i buy the disk, usually!
