20) GNARLS BARKLEY, THE ODD COUPLE

A batch of "Crazy" sequels would've made more financial sense. But the world's most depressing party band dialed back the sticky choruses and upped the cinematic self-doubt and loneliness, with Danger Mouse's beats and backdrops providing gorgeously slippery ground for Cee-Lo's soulful ruminations. The raspy frontman is both amped (the shimmying "Run" and "Going On") and mournful (the trip-hoppy "Who's Gonna Save My Soul"), but nearly always shattering.
