Coldplay are going to be in Guitar Hero. Coldplay. I'll give you a moment to emit a deep, remorseful sigh. As part of the promotional circus surrounding their latest album, the song "Violet Hill" will be made available as DLC for Guitar Hero III, though a date for its release has yet to be specified. Coldplay frontman Chris Martin says of the song, in all seriousness, "It's not [all] about the piano shit". Come now, Activision. It wasn't enough to kill Guitar Hero, you now gotta whizz on its freshly-covered grave?
