13. Leonard Cohen, 'Old Ideas'
At 78 years old, the dapper Canadian sage came back to whisper his heavier-than-ever poetry about sex and spirituality, complete with bedroom scenes like "I'm naked and I'm filthy/And there's sweat upon my brow." As a man who never really sounded young he was well into his thirties when he dropped his classic debut album in 1967 – Cohen adapts to this uncharted age with a lifetime's worth of grace and wit. Best lines: "I dreamed about you, baby, you were wearin' half your dress/I know you have to hate me, but could you hate me less?"
