@django@discuss.tchncs.de in the comment section pointed out that fedivision already happened in the past. It seems like fedivision worked fine with fully original content so I might just make the contest about original songs to save on copyright headache. I'll probably just call it a continuation of fedivision with the same name.
Regarding the Avril Lavigne lawsuit, it happened during the times when music industry was particularly being assholes, but I get what you mean: we can never guess how far billionaire protection ahem copyright laws can go.
