No discussion for this one?
This is a really tough call. I think the one from New Super Mario Bros fits the style perfectly, for obvious reasons, except for the "BAH!" every so often. Could someone edit up a version that removes them, and post it? I think with it removed, it would be good.
The Zorah remix is also good, and would be consistent since we will probably use his work for at least 1 other song. If hamradio could swap out some of the sounds that are out of place, I think it would also be good.
I think the Brawl one sounds good, but it is too over-the-top to be used ingame. If we used brawl music for all of the stages, then maybe, but to use other music for all the others, the Brawl version will sound really out of place.
