Announced as a Rock Band Network release during PAX East, the Joystiq Podcast opening theme, "Gravity (Don't Let Me Go)," is now available for the Xbox 360 version of the Rock Band platform for 80 ($1). As with all RBN releases, the playable song can be demoed before purchase. The RBN version of the track, an update of the show theme, was authored for the game by TheMainDrag and will appear on Jon Black's upcoming EP The Beginning (Up From The Ground Vol. 1), available April 27.

Joystiq Podcast host Justin McElroy wants fans of the show and of music to download the track immediately, saying, "If you're not using your fingers to play 'Gravity (Don't Let Me Go)' on Rock Band, just cut them off and choke yourself with them."

RBN currently hosts around 210 songs, which are listed here. Now go drop "Gravity" onto your console.
