7. Drake, 'Thank Me Later'
Arriving after three years of mixtapes, guest spots and merciless hype, the debut LP from the Canadian actor- turned-rapper delivered the goods with sumptuous beats, airtight rhymes and nuanced introspection. Drake's sleepy, soulful flow gave his morning-after reflections on the high life an undercurrent of irony. He's the definitive star of hip-hop's tortured post-Kanye era: a guy who can't quite decide if "I've been up for four days gettin' money" is a brag or a burden.
