Last year, Harmonix and MTV Games promised that their rhythm game duet Rock Band would feature full downloadable albums, with The Who's "Who's Next" one announced offering and Nirvana's "Nevermind" a heavily rumored second option. However, these albums were conspicuously absent from the game's launch lineup of downloadable content, and months passed with no word of when they would finally arrive.

　　Last month's Boston six-pack of songs came a single track shy of a full album, but next week Harmonix is finally set to make good on its prelaunch promise with the release of Judas Priest's Screaming for Vengeance in its entirety. The 10-song album will be available Tuesday on the Xbox Live Marketplace and Thursday on the PlayStation Store, with an asking price of $14.99 (1,200 Microsoft points).

　　Screaming for Vengeance features the group's biggest hit, "You've Got Another Thing Comin'," as well as "Electric Eye" and "Pain and Pleasure." All 10 songs will be the original Judas Priest master recordings, and they will be available individually for $1.99 (160 Microsoft points), although the 41-second track "The Hellion" will be included in the "Electric Eye" download.

　　Since the launch of Rock Band, Harmonix says customers have downloaded more than 8 million songs for the game, with a playable catalog of roughly 140 tracks between the original disc and downloadable content.

　　[UPDATE] Newsweek's Level Up blog is reporting on the next two album downloads to follow Screaming for Vengeance. According to the article, next month will see The Cars' self-titled album released, followed by The Pixies' Doolittle in June. As for the album prices, the site reported that they will vary depending on the number of tracks included.
