Funny enough, this was on my first attempt today. I've tried several times in the past, but to no success. I just happened to get a million master score this time. Near the end of the song, part of me was getting nervous I would mess up, and the other part of me was waiting for me to mess up. Luckily that didn't happen. I can guarantee to you that I won't ever be able to MM this level again. I'm convinced this (and my MM on Brain Power) was a lucky fluke.
(Also side note but this is the biggest combo I've ever had in this game)
