Hey, Rock Band aficionados! Are you ready to spend your hard-earned Microsoft Points, Wii Points or good old-fashioned cash money on tracks which you'll never be able to play without injuring your tender, fragile metacarpals? Brace your bones -- the Music Store is about to get a healthy dose of Megadeth, in the form of the outfit's 1990 album "Rust in Peace." Or, as it's more commonly known, "The one with 'Hangar 18' on it."

The nine-track album will be available for $14.99 (1200, bundle not available on Wii), and can also be purchased piecemeal for $1.99 (160, 200 Wii Points) per track. In addition, the Who's "Super Bowl S-mashup" medley will be made available on Sunday after the big game for $1.99 (160, 200 Wii Points).

Check out all the songs included in next week's update after the jump.
