This duo – Malawian singer Esau Mwamwaya and Swedish-born producer Johan Hugo – are so well-suited to produce hipster accolades, they invite suspicion before you’ve heard a note. But MTMTMK dispels doubts, improving on the debut with bigger hooks – see “Rumbae,” a synth-lashed dance track fun (and dopey) enough to fit into David Guetta’s DJ sets.

“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.
