Worth Playing: "The Karaoke app may not be perfect, but it's still plenty enjoyable. It's not meant to compete with your Rock Band library. If you think of it as a replacement for that, it fails. But as a party game, it's killer. One of the biggest complaints with music games at parties is the lack of selection. Karaoke makes library diversity a non-issue. Stick with traditional music games for songs you love. Purchase time with Karaoke when you've got a large group with varied tastes. Since it costs nothing to download, you might as well give it a spin."
