Actually sounds like a menu screen track off from Final Fantasy
I haven't played a FF in forever but the beat oddly reminds me of the one for the original playstation and there was a dude with a huge sword that was a gun. All I can really remember haha.
Also, I like to think the whole song is tongue n cheek, poking fun at everyone that constantly calls him fake for doing the music game. Dunno, maybe that's just me.
