Colorfull Channel is a new "theme" and sequel for "Colorfull Canvas". (Which it's also a theme.)
The Pop'n Music-like theme will again have new music (assuming about 40 tracks as said in homepage) and characters...
And i'm not sure, but are they also planning to make a theme with re-releases of Colorfull Canvas songs for Toy Musical? O_o
Whats amazing so far if the theme is more "lively" like Pop'n Music. *o* (AKA has a bit of animation to the skin.)
