Muse's sixth album, The 2nd Law, polarized the band's massive fan base. Some felt they had finally taken their Queen-on-steroids sound too far, and others were dismayed at their open embrace of dubstep. Most fans, however, felt it was a logical step forward, even if some songs did push the boundaries of their sound a little much. Hell, if every song was a remake of "Knights of Cydonia," they just wouldn't be a very interesting band. The second single from The 2nd Law, "Madness," doesn't stray that far from Muse's signature sound. It's a fascinating mixture of Depeche Mode, George Michael and even some R&B. The song didn't go higher than number 60 on the U.S. Hot 100, but Muse has never been a real singles band.
