Activision is set to offer seven new songs in various downloadable content packages during December on both Xbox 360 and PS3.
A Warner/Reprise Track Pack is being prepped, and set to include Linkin Park's "No More Sorrow", Mastadon's "Sleeping Giant" and The Used's "Pretty Handsome Awkward", all based on master recordings.
Single-song downloads are also planned from "European bands", including Extremoduro's "So Payaso", Trust's "Antisocial" and Die Fantastischen Vier's "Ernten War Wir Säen".
Finally, Activision is set to release a free "exclusive rock rendition" of "We Three Kings" recorded by Steve Ouimette.
Pricing for the others has yet to be specified, but track packs typically cost 500 Microsoft Points on Xbox Live Marketplace and USD 6.25 on the PlayStation 3 Store.
So, look out for those soon. We've asked Activision for more details (and details on when PS3 owners can expect some of the other DLC already out on Xbox 360), and hope to hear back soon.
