The downloadable music for Activision's rhythm games in the Guitar Hero, DJ Hero and Band Hero series will no longer be available after the end of this month on March 31. The production of DLC for the brands ended in February 2011.

The announcement comes from an update on the publisher's Facebook page, which clarifies that the Guitar Hero servers will remain online and that previously-purchased content will be unaffected. As an encore, selected songs and track packs will be discounted by as much as 50 percent on Xbox 360, PS3 and Wii until the end of the month. Additionally, the Guitar Hero game on iOS will be discounted through the end of the month on the App Store. [Image: Activision]
