It seems hard to believe, but Madonna‘s second studio album Like a Virgin turns 30 today. The groundbreaking pop LP did more than establish the Material Girl — single No. 2 off the record — as a cultural phenomenon, it defined a decade. After Virgin, Madonna became a style and music icon; her rough-and-tumble yet glam look was mimicked by teens around the world. With the record, Madonna became arguably the world’s first dance-pop superstar. Oh, and the best.
