New to the PlayStation Store this week is downloadable content for Neversoft's Guitar Hero III: Legends of Rock, Harmonix's Rock Band, and Idol Minds' Pain.

Rock Band aficionados can now download three new Nine Inch Nails master recordings, including "The Perfect Drug", "The Collector", and "March of the Pigs". All three tracks are priced separately for $1.99 a piece, or as a bundle pack for $5.49. The tracks were made available on the Xbox Live Marketplace earlier this week.

PS3 owners who get their kicks with Guitar Hero III: Legends of Rock now have access to three No Doubt songs, which include "Don't Speak", "Excuse Me Mr", and "Sunday Morning" as performed by the band. The tracks, which are not sold individually, can be purchased in a bundle for $6.25.

Finally, a new playable character for Idol Minds' Pain, Scurv Dogg, is now available to download for a price of $0.99.
