Man, I love the SSBB main theme. Fucking epic.
I know it's been said about other tracks, but the Pokemon Stadium track sounds WAY too slow to battle to. Oh well, I like what they did with the ending evolution music.
Yeah, it sounds slow, but I bet it'll fit in fine when you play. There are some songs in Melee that sound slow as well but work fit during gameplay. I wouldn't be too worried about it. Even if it doesn't, you can still choose not to play it with their new feature, so no worries.
Holy fucking shit triple music update. Also I never knew Nobuo Uematsu composed the main theme...
Maybe Uematsu's involvement means a FF character/item/stage? He wasn't included on the original composer list though.
When Sakurai put up the list of composers, he said:
This is dangerous. It's a little risky.
A lot of people thought this meant that it could give people insight into which games characters, items, and stages would come from, which is why Sakurai was reluctant to put it up. Probably means nothing, but it'd be cool if it did.
