You'd need some pretty powerful "Don't show me this again" technology for that, though.

Well presumably you'd only load this song/songs onto the player once. And even then after that it wouldn't be inconsistent anymore. The next time you tried to load one of the industrial gothic tunes it wouldn't ask because the genre would already be there. So then it would only ask if you did Caedmon's Call that wasn't either "Christian" OR "Industrial Gothic". (Which, BTW, is a really funny notion if you ever hear Caedmon's Call). Your only real problem would be groups that constantly genre shift (and I can't think of many of those).
