This is one of those things that is so close, yet so far. It is basically Karaoke for the XBox with some half-baked features thrown on top.
The kids really liked just yacking into a microphone while their CD's played. They weren't familiar with any of the built-in songs - neither was I for that matter. The cool thing about the program is that it will record what you're singing and you can play it back later - the kids really thought that was cool. The problem is that it wouldn't do that if the song came from your own CD. Lame.
The visualizations are cool. All in all this is a fun title for the kids that could have been a lot better. I am glad it only cost me 20 bucks.
There is a way to connect it to your PC to download music and photos. This feature is implemented very poorly. I never got it to work because I got sidetracked after 5 minutes - it didn't look like it was going to be particularly useful anyhow. It also has this Rave mode that we didn't try yet.
