After completing Subspace Emissary (Super Smash Bros. Brawl), I unlocked and was presented with four or five music tracks. A few of them were the Step tracks (like "Step: Subspace" and "Step: The Plain") and a boss battle song or two (esp. the song during the Tabuu fight).
I thought these songs would play on Battlefield or Final Destination, but they aren't listed there. I can't find them on any stages, actually.
So does anyone know where these songs went? If I can't play them in a stage, where can I listen to them, at least?
