Each week Harmonix releases new songs for Rock Band. However, due to the tenuous nature of licensing deals, DLC is often not announced until the last possible moment. As fortune would have it, your pals at IGN stumbled onto an Xbox.com page listing upcoming tracks for January.
The list includes tracks for the final two weeks of the month. Song packs run $5.49 (440 Microsoft Points) with individual songs costing $1.99 (160 MP) each.
Joystiq's note: "barring any unforeseen hiccups, we're assuming that the songs will be available on PSN as well."
