Here’s the next bunch of new downloadable tunes from RedOctane for Guitar Hero II on Xbox 360, once more cherry-picked from the original Guitar Hero.

Content Pack 1:
"Cowboys From Hell" - Pantera
"I Love Rock & Roll" - Joan Jett & The Blackhearts
"Cochise" - Audioslave

Content Pack 2:
"Godzilla" - Blue Oyster Cult
"I Wanna Be Sedated" - The Ramones
"Sharp Dressed Man" - ZZ Top

Content Pack 3:
"Iron Man" - Black Sabbath
"Take Me Out" - Franz Ferdinand
"Smoke on the Water" - Deep Purple

Oh, did we mention that this is all currently filed under ‘rumour’. The Activision PR guy we just spoke with couldn’t confirm or comment, blah blah blah.

However, the source of the rumour – HarmonixFans.com – is pretty solid, so SPOnG will eat our sweaty rock headbands if this should prove to be false. We'll confirm with release dates shortly though.

We imagine the pricing will be the same as the first bunch (500 MS Points for a bunch of three tunes), which will no doubt get the nitpicking penny-pinchers moaning again.

Check Guitar Hero II for all you need on Red Octane's glorious air-guitar replacement therapy.
