A mid-1950s Harry Belafonte hit. An early 1990s dance-club smash. A crunk anthem. A thumping Eurodisco beat, some Auto-Tune. These are just a few of the bits and pieces that Jason Derulo crams into "Don't Wanna Go Home," the single from his second LP of party-hearty robo R&B. Derulo doesn't travel light; on nearly every song he stuffs his suitcase until the seams split. "Fight for You" tricks out a power ballad with a refrain from Toto's "Africa"; "Breathing" tosses in tribal vocal chorales. But Derulo is endearingly into it – he attacks the songs – and he can sing. (Check the falsetto flutters in "Dumb.") He's just a bit too overeager – too determined to please all of the people all of the time.

“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.
