The latest leak from Camp Kanye is less a song than an inspired chunk of Nineties-style DJ mixology. It begins with Bon Iver — the Wisconsin-bred folkie who collaborated on nine songs for West's upcoming album — singing a revamped version of "Woods," his haunting, Auto-Tuned meditation from 2009. Vocal rounds swell into a gospel chorus, fat 4/4 drums kick on, and there's Kanye pledging, "If we die in each other's arms/Still get laid in the afterlife." (Trés romantique!) Then, Kanye peels away the lushness, switching to a conga beat and sampling Gil Scott-Heron's 1970 "Comment #1" at length. Scott-Heron's radical poetics about a nation "now blood and tears instead of milk and honey" are a perfect contrast to the gorgeous heartbreak of Bon Iver, and overall, "Lost in the World" is the sound of a hip-hop icon on a wild creative bender: dizzying, sometimes baffling, perpetually spectacular.

“Help Me”

Joni Mitchell wrote and recorded this song for her album Court and Spark, but she had to switch from her regular band to make the song sound exactly the way she wanted. "I had attempted to play my music with rock & roll players," she told Rolling Stone. "They’d laugh, 'Awww, isn't that cute? She's trying to teach us how to play.'" Mitchell switched to a jazz band, Tom Scott’s L.A. Express, and scored the biggest hit of her career in the process.
