I'm not 100% sure if this is what you're looking for but I'd figured I'd share...I remembered on slippyToad's thread (
http://forums.ffshrine.org/showthread.php?t=78848&highlight=) he had some Wii music (

Good luck, I hope it's what you're looking for
Thanks for linking those, I forgot about them. That specific link wasn't quite what I was looking for, but it does look like slippyToad does have the other channel music I was looking for. Thank you! Also, I love your name. x'D
