I've actually gotten two different albums on Amazon in just the last couple months, just from prospective RBN projects.
....which means I can't actually say who they were. >_< Lachesis knows one though.
I do jump on as many free albums as I can. Buying albums, you enter the question of "do I want to spend my money on this".... free albums, I'll gladly suck up some of Time Warner's bandwidth for that!
