Microsoft threw their hat into the karaoke ring with Lips, bundled with two gorgeous mics (one black, one white) and song choices complete with the authentic music videos and a diverse selection of tracks for listeners with varying tastes. It hasn't experienced the longevity that was likely projected for it, but it was a fantastic, more realistic attempt at karaoke that even picked up on vibrato and other singing styles. It's a shame the project was dropped -- the handful of sequels it spawned doesn't exactly whet our appetites.
