The French dance-floor duo lay it on thick with staccato disco strings, slap-back synth bass, metal-machine sonics and an in-your-face pulse until the groove rocks both harder and stranger than the original. Now it's worthy of Timberlake's confession, "She's freaky but I like it."

“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.
