Very complex! And tagging would be a nightmare, so I don't fault you for doing only as much as you need to at all (less paperwork = GOOD). If I had to try and classify this, it would probably be primary fandom:spn, secondary fandom:glee, but I can do something like that because I'm not dealing with gigantic amounts of recordings like you guys :) I can imagine the nightmare ensuing..

Either way you'd hope people wouldn't just download things willy nilly without at least checking out the summary first, or if they do, to be pleasantly surprised at what they hear :D I must say, I've yet to hear any negative criticism on it; you'd have to be pretty offended to come back and compose bad press.
