This dreamy extended workout by the British electro-pop act throws in dime-store synths, drum-machine thunderbolts and a sample from the titular instrument. But it doesn't hit its moody-disco mark until Alexis Taylor's haunted vocals kick in, casting a pall that can only be danced through.

“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.
