Miror B's battle theme from Pokemon XD: Gale of Darkness with enough cheese to drown the thickest of nachos. Basically? I tried to arrange this song as cheesily as I could, taking a bit of vague inspiration from disco along the way.
I'm not sure if it tops the original, but I tried! I woke up this morning and literally started freaking out a little because suddenly I wasn't sure if the guitars or the piano were too loud during the peak. "Hey, why don't I spend another couple of hours fiddling with with that and recompiling?" orz
