Okay, let's be honest: just about every person on the planet has cranked "Rolling in the Deep" up to maximum volume and rocked along with Adele's soulful kiss-off anthem at one point or another. On "Rolling in the Deep," Adele found celebration and resilience in her broken heart, and the song rewarded her by turning her into a global superstar. Adele's go-for-broke vocal performance is a big part of why "Rolling in the Deep" ever caught on, but Paul Epworth's booming production is the element that has kept us playing it two years after-the-fact. "Deep" simply isn't a song you can switch away from when it comes on the radio if only because it sounds so damn good when played on an expensive stereo system.
