Well, I can see why: Smashing Live. When Nintendo gives another Smash Bros. concert, I bet the orchestrated versions then will be even better than the game's adaptations. Then, of course, you can use the third party character's music if it isn't in the game, and things like that. Oh, and the millions of songs that just won't be in the game. If you like any of them, you can listen to those, too.
