The announcement of another Rock Band 3 DLC pack has fans hopeful that the once much-loved rhythm franchise is about to make a comeback.

Rock Band developer Harmonix has announced two new tracks, both of which fans have interpreted as double entendres.

In a blog post announcing the DLC, Harmonix hinted that both tracks have "great titles".

Tenacious D's "Rize of the Fenix" and Weezer's "Back To The Shack will be available for PlayStation 3 and Xbox 360, for US$2 each.
