The official Japanese site for Wii Music has been completely revamped, and now it offers a ton of videos to check out. I don't know...but some of the videos on this site actually got me interested in Wii Music! You really see the range of things you get to do, and honestly, some of them look fun. I didn't know that a website update would manage to sway me in the other direction with Wii Music!

Site here (thanks Creamsugar!)

There's also been a developer's voice interview update concerning Wii Music, but it's completely in Japanese. If you want to check out some pics of Miyamoto and Iwata, and plug away at a machine-translated version, then by all means, follow this link!
