I've got several Karaoke games (American Idol, Rock Band, etc.) for my Xbox 360, but I've heard that Lips lets you import your own MP3 files and play them in the game.
My wife does community theater, and I was thinking for her musical numbers this game would be a good way for her to practice the songs for her plays and perfect her pitch and timing on the songs by importing and playing professional recordings of those songs.
Obviously it doesn't have the lyrics if you import your own sound file (especially for obscure music), but can it detect and show the pitch indicator on the screen for imported songs? Overall, would this game be practical for singing practice on imported songs?
