Madonna proved to be one of the definitive artists of the 80s, a source of both massively popular hit songs and a beacon of controversy for her confident portrayal and unashamed acceptance of sexuality. Like a Virgin, her sophomore release, was the big one, the album that propelled her popularity all the way into the stratosphere, boasting four singles to reach the top 5 on the Billboard Hot 100 and aided by healthy rotation on radio and the still new MTV. It was the album that made Madonna a household name and a pop superstar. It was also an early all-digital recording, with the compact disc released simultaneously with the vinyl version - a first at the time. So how does the original CD release hold up today, in comparison with the reissue version of 17 years later?
