Activision appears to be learning a hard lesson about the risks of tying a music game to a subscription service. The publisher has launched a "voluntary refund program" for Americans who can prove they bought Guitar Hero Live between December 1st, 2017 and January 1st, 2019. You can make a claim until May 1st, 2019. While Activision didn't say why it was offering refunds, it's likely tied to the end of the game's Guitar Hero TV streaming music service. The company shut down GHL's streaming component at the end of 2018, shrinking the song library from 484 songs to the 42 tracks on the disc -- you suddenly weren't getting what you paid for.
