I actually started several of the composer pages and added music that was explicitly confrimed to be made by them, but there have been some other users that have being adding "song guesses"; if they have claimed to contact Nintendo composers, then I'd like to see proof of that because Nintendo is not really the kind of company that shares that kind of info at such an explicit level with outsiders. There have actually been some song credits in some official soundtracks / game sound tests / etc. (they are mostly accessible through VGMdb), but unfortunately Nintendo doesn't really release a lot of their music.

Anyway, they could be actually right, but I'd rather treat the info that isn't officially confirmed as speculative for the time being (on a personal level, I disagree with some of the song credits, but that comes from my very own opinion having a general idea of the composers). If any official info ever gets public, however, I'll be sure to correct that.
