I personally love Mario's madness, but also that new silly billy thing is great too, I say on a scale I put Mario's madness on top, Sonic.exe second, and Silly Billy (or hit single) third.
It was referring the game named “Sonic Triple Trouble” where there were 3 villains, Knuckles, Fang and Eggman, but the song has…4 villains?…I guess it’s because of 3 souls but then there’s just Sonic.
