Taken from an official DVD :P

I'd like to see it in action, but I think, that we still beat it some fields. We've got most song from the show, some fan ones and a few in different languages (currently: 1 French, 1 German and 3 Polish).
Also, we've got rating system (implemented in Ultra Star) and each note is shown while singing, so everyone can not only learn the lyrics, but also improve their singing.
I say: let's continue with the project.
Oh, of course! My Little Karaoke is way more content-rich, feature-full, and fun to play than the sing-a-long songs on the official DVDs. :)
Plus, the official stuff is never going to have fan-made songs or videos in it. :)
