Warner
From Bluesockapedia
Warner are a division of Hell, they are also Muse's record label, therefore by signing with them they actually sold their souls to the devil. Although they hope to escape this contract by sacrificing MCR by showing them up at every gig they play together.
This contract with the devil has furthered their career by letting them play the best gig in the world ever at wembley stadium. Many fans believe that this would have happened anyway though, and that this contract has done far more harm than good
