The title pretty much says it all. Itunes has the full karaoke version of the TMM theme song! (My Sweet Heart)
Heres the link: http://itunes.apple.com/us/artist/tokyo-mew-mew/id275680275
I had my hopes up when I checked the store out, and they were, er, almost pleased. The only thing I wished itunes had was the theme song with the Japanese Singer's voice.
