I don't know about Viacom's channels, but I swear nearly every major label musician/artist's channel that I've been to lately has had at least one of their videos missing due to a takedown request from their own record company. That said, most of the channels that I looked at were run by the artists themselves, I guess it wouldn't happen so much on marketing-dept run channels, but it wouldn't surprise me if it did.
