nWo's theme ("Rockhouse") is definitely a production. I forgot which library it's from, but it's one that WWE no longer has access to. WWE pays a solid (and hefty, at least to us) monthly fee for unlimited access to a certain number of production libraries, and "Rockhouse"'s library is not in that list apparently. (The reason why they could still use Booker T's was because it happened to belong to a library that WWE had access to, Kosinus Music.)
