Drug references aren't that big on this game, surprisingly."Black Umbrella" may have a bit too many drug references to get through.
I think the Nazi line may have to be censored. I've seen another song in Playtesting that had Nazi references get altered next round to have them removed. But that's one censorship, which can still live on with the game.Gang Fight shouldn't really have a problem though, unless the "pleasant Nazis" line is somehow too offensive.
I think it'd be great to get as many of these songs on here as possible.
