Gliding between styles with a grin, Bruno Mars is a true pop auteur. As a songwriter, Mars is a human jukebox loaded with hooks from every decade, racking up retro hits like the pulse-pounding rocker "Locked Out of Heaven" and adding bumping hip-hop breaks to the sweetly earnest "Just the Way You Are". But while Mars may have mastered his behind-the-boards skills by looking the past—whether to the time-tested Motown playbook or electrifying post-disco R&B—even his delicious throwback jams like "24K Magic" have a luscious flavour that's pure 21st century pop delight.
