37. Muse, 'Madness'
The U.K. prog-rockers went Kid A with this year’s The 2nd Law, but this was the LP’s pop-ready cherry – all sweet Bonoish crooning by Matt Bellamy, electronically distressed backing vocals and deep-space bass wobble. Then the guitar rips in and brings it back to Earth. Chris Martin called it their best song ever; we agree.
