50 Cent, "In Da Club" (2003)
By the time "In Da Club" dropped in January 2003 at the height of rap's mainstream dominance, 50 Cent's Get Rich or Die Trying was the most anticipated rap debut since Snoop Dogg's Doggystyle. It topped the Billboard charts for an impressive nine weeks, and turned into Dr. Dre's biggest hit as a producer to date. Its nightlife ubiquity around the globe endures, thanks to its medley of operatic keys, and a hook from 50 that virtually commands you "find him in the club." "As soon as he walked into the studio, he picked up a pen, and we were done in an hour," Dre told RS in 2003. The beauty of "In Da Club" is its charming simplicity. 50 sounds like a thug comfortable in his own skin, and someone who can party just as easily as "crack your head with a bottle of Bud" if you step out of line.
