Kay. I'll give it a go. Next question: I want to use a certain soundtrack for my outro. I've been waiting for this group to email me back, but they haven't. If the song is copyrighted by them, but I give them full credit and acknowledge that the song is theirs and not mine, I can still use it, right?

Haha, that's funny. I wish. More than five seconds of copyrighted audio gets you an auto content ID match.
