There's a lot of legal downloads out there. Far, far more than you could ever use in a lifetime.
I alone have 30 gigs of legal stuff few, if any, other people have to offer.

Also, don't forget that in some countries (Canada, for example) downloading of everything is legal
even if the MAFIAA control freaks don't like it.
