It's not enough just to play games anymore. Nowadays, you have to watch them too. That just got a little easier on the Xbox 360, thanks to a new Twitch.tv app. The streaming app is now available for Xbox Live Gold subscribers, offering "access to 300 of the most popular streams," including tournaments, all organized by game or popularity.

Twitch will host a special live broadcast with Xbox Live guru Major Nelson following next week's "Xbox Revealed" event on May 21. The broadcast will air on Twitch.tv and the Twitch app on Xbox 360, beginning at 3pm Eastern. The event itself, incidentally, starts at 1pm Eastern. Tune into Joystiq for lots of live coverage.
