Someone on these forums (almeeker or cjohnson ? ) raves about a dance game for the Wii. What is the name of it again?

I am considering getting it as a family gift for Easter.

Thanks!

Just Dance 2 - I just got it recently (on sale at Walmart) and my kids and I have been having a lot of fun with it.
I think there's another one that someone else was raving about too.
