On the lead single from Evanescence's third album (and first in five years), Amy Lee trades anguish for defiance, goosing her wail with welcome sass. Still, she's nearly overrun by the music, a collision of two-ton guitars, strings and piano.

“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.
