Maroon 5, art rockers? These remixes of the group's hits by indie acts like Of Montreal and Deerhoof make the idea seem oddly plausible. Maroon 5's bubblegummy pop — and Adam Levine's anodyne vocals — make the band ideal candidates for remix treatment, and they've corralled some impressive extreme makeovers: hip-pop (Swizz Beatz), Euro-dance (Bloodshy & Avant), crunk (David Banner), retro R&B (Mark Ronson). The best are counterintuitive: Deerhoof's blip-heavy take on "Goodnight Goodnight" might just convince Levine to quit Hollywood life for artsy bohemia.

“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.
