The second wave of downloadable content for Harmonix's Rock Band (PS2, PS3, X360) arrived on the Xbox Live Marketplace this morning, once again fulfilling the developer's promise of weekly track releases for the multi-instrument rockathon.

As previously reported, this week's additions bring three more David Bowie tracks to the game. Of them, "Moonage Daydream" is a master track performed by the man himself, whereas "Queen Bitch" and "Heroes" are covers.

"Moonage Daydream" hails from Bowie's beloved "Ziggy Stardust" album, as does "Suffragette City," which one of the 58 songs included with the game. Many are hopeful that the full album may one day be playable in Rock Band a la the upcoming release of The Who's "Who's Next".

Each song sells individually for 160 Microsoft Points ($2), with the three-song bundle offering a slight savings at 440 Microsoft Points ($5.50). The tracks are expected to be available to owners of the PlayStation 3 version later this week, but will not be an option for those than pick up the PS2 edition--slated to release December 18--due to the system's lack of substantial storage capacity.
