We've known about the Green Day three-pack for a while, but more tracks were just announced today to give the week of July 7th a good dose of brutality. Alongside three songs from Green Day's 21st Century Breakdown is an eight-pack of artists playing the Rockstar Mayhem Fest. This includes Slayer, Cannibal Corpse, and Marilyn Manson. Warm up your fingers and crank your speakers loud; this week is sure to piss off mom and dad. Full details, including tracks and pricing, after the jump.

As expected, next week brings a second Warped Tour pack (though this time with only three songs), along with a 3-pack from arena rockers Foreigner and a single track from Black Rebel Motorcycle Club.

Along with previously mentioned Thrice and The Devil Wears Prada, the Warped pack features Dear and the Headlights.

Check below the fold for a full listing of tracks & prices. 

For Rock Band next week, we'll be getting the first of two rumored Warped Tour packs, featuring artists playing on this year's tour.  In addition to Bad Religion and Underoath (who each have one song available for Rock Band), you can expect to see RB newcomers A Day to Remember, Chiodos, and Escape the Fate in the pack as well.

If that's not your thing, a 3-pack from pop-rock band Maroon 5 will also be available.

If the Warped Tour newsletter is correct, there is another Warped Tour pack coming the week after next, featuring artists Thrice and The Devil Wears Prada.

Next week you'll finally be able to turn things up to 11 in Rock Band when a four-pack from iconic (and semi-fictional) rockers Spinal Tap arrives at the Rock Band store.  Additionally, you'll be able to grab a 3-pack from Evanescence.

Three of the four Spinal Tap songs are from their new album, Back From the Dead, which also is releasing next Tuesday.
