In its first 40 weeks on shelves, the original Rock Band saw a grand total of three downloadable albums released for it. Rock Band 2 will meet that mark in its first three weeks at retail.

Since its Xbox 360 release on September 14, Rock Band 2 has added full album downloads for Megadeth’s Peace Sells...But Who’s Buying? and Rush’s Moving Pictures. Today, Rock Band developer Harmonix announced on the game’s official forums that next week’s downloadable-content update will be the Red Hot Chili Peppers’ classic album Blood Sugar Sex Magik, featuring such hits as "Under the Bridge," "Suck My Kiss," and "Breaking the Girl."

One of the album’s biggest hits, "Give it Away," was included on the Rock Band 2 disc. The remaining 16 songs (the most tracks of any Rock Band downloadable album to date) will be available on Tuesday for the Xbox 360 and Thursday for the PlayStation 3. Songs can be purchased individually for $1.99 (160 Microsoft points), or all together for $19.99 (1,600 Microsoft points).

All downloadable tracks are compatible with both Rock Band and Rock Band 2. The complete tracklist of the album (minus "Give it Away") follows:
