The Rock Band music library continues its steady growth with the inclusion of four Lenny Kravitz tunes, and a couple of songs made by mercenary Harmonix employees who insidiously aim to exploit the game's success in order to further their musical careers. The Kravitz is represented by "Are You Gonna Go My Way," "Freedom Train," "Let Love Rule" and "Mr. Cab Driver." These songs will go for $1.99 each or $6.99 for the pack.

The Harmonix bands are Megasus and Honest Bob and the Factory-to-Dealer Incentives, and they're dropping the songs "Megasus" and "Entangled" respectively. Unsurprisingly, these lowlife hustlers are selling themselves cheap at $0.99 a pop.
