I've been looking for the music from the Wii's non game channels. Specifically

Mii Channel
Photo Channel
Wii Shop Channel
Forecast Channel
News Channel
Internet Channel
Everybody Votes Channel
Check Mii Out
Nintendo Channel

I'm looking for Wii menu intros, as well as songs during use. I have a few songs from Smash Bros releases, but I can't find the majority of them.

There are some other channels that I don't know if they had any exclusive music. Any of the following with something unique would be a nice bonus.

Metroid Prime 3 Preview Channel
Wii Fit Channel
Mario Kart Channel
Skyward Sword Save Data Update Channel

Any help is appreciated.
