OK, one more source for obtaining the Betallica FLACs: SoulSeek.
Actually, I have no idea what SoulSeek even is, I assume it's a P2P of some sort. But on the Beatallica boards, they have a sticky with information regarding the
Beatallica SoulSeek Chat Room, and they make everything available there.
{Note to mods: Beatallica does not sell their music, they only make it available for free download, so this is legal.}
