“Guitar Hero III” fans: new songs for you!

The Modern Metal pack let’s you “jam” to master recordings of Deftones’ “Hole in the Earth,” Avenged Sevenfold’s “Almost Easy” and Thrice’s “The Arsonist.”

And, in honor of St. Patrick’s Day (Monday), you can also download a free track pack from Celtic punks Dropkick Murphys. Straight from the band’s sixth album, “The Meanest of Times,” you’ll get the master recordings of “Famous for Nothing,” “(F)lannigan’s Ball” and “Johnny, I Hardly Knew Ya.”

It’s all available on Xbox LIVE Marketplace and on the PLAYSTATION Store.
