User blog comment:Raymond Li/Musical Crossover thoughts/@comment-26412696-20160818140256

As @Rafe Adler pointed out, Music Meister is, most likely, the villain of the crossover. He (or a villain with a similar subset of powers) would be the best way to do the crossover while keeping it in canon. Besides, musical episodes of some serious shows have been great in the past - ever watch Buffy the Vampire Slayer? And that was all kept within canon, too!

I guess what I'm saying is, try to keep your chin up, okay?
