Activision's library of downloadable song DLC for Guitar Hero, DJ Hero and Band Hero will be taken offline at the end of this month, the publisher has announced.
The Guitar Hero mobile game will also be removed from sale on 31st March.
Servers for the PlayStation 3, Wii and Xbox 360 games will stay online, however, and any tracks you have already purchased will of course be unaffected.
"We want to thank all of you for supporting Guitar Hero over the last nine years," Activision wrote in a statement posted to the official Guitar Hero Facebook page.
"To celebrate this great community, selected songs and tracks will be available for as much as a 50 per cent discount on Xbox 360, PlayStation 3, and Wii from now until the end of the month. For more information, please visit the store on your console."
Guitar Hero and its spin-off franchises remain in limbo, with no new games on the horizon. Activision previously admitted not treating the franchise with the right amount of "nurturing and care" needed to sustain long-term sales.
The long-since-cancelled Guitar Hero 7 would have removed the franchise's band support and instead focused on a new six-string guitar peripheral. The project was canned before ever seeing the light of day.
