Singing at your TV may not be as much of a big deal now as it was during the Rock Band/Guitar Hero heyday, but it's still a fun enough diversion at parties to warrant Microsoft partnering up with The Karaoke Channel for the upcoming Karaoke app. Users will have access to a library of over 8,000 sing-along tunes to bring parties to a crashing halt with.
The unusual twist here is the payment model. Karaoke isn't an Xbox Live Arcade download that you can just buy with MS Points. In actuality, it's a new free-to-play exercise. Users will be able to spend MS Points on multi-hour blocks (2, 6, or 24) of Karaoke functionality, with full access to anything in the song library during a rented time block.
Karaoke features Avatar integration with your virtual self singing and strutting on the screen. Microsoft is also planning to offer SmartGlass features and Achievements in Karaoke, with the service expected to launch sometime this holiday season.
