After reinvigorating their careers by serving as vocal coaches on NBC's reality show "The Voice," Maroon 5's Adam Levine and Christina Aguilera continue playing all the right cards on their new collaboration, "Moves Like Jagger." After the song opens with a catchy whistle layered over a strumming guitar, a thumping bass drum and lead singer Levine's smooth vocal approach have the listener hooked. "Jagger" remains playful with lines like, "You say I'm a kid, my ego is big, I don't give a shit," while also nodding to the Rolling Stones frontman's infamous stage presence. Aguilera arrives in the track's bridge, giving the song an exciting change of pace by harnessing her vocals before unleashing some signature growls in the final chorus. The two artists have updated the sounds from their last albums for a refreshing new track that's sure to flourish on radio.
