Query: No Sophomore slump here!

An artist's biggest fear: The sophomore slump.The industry's nickname of when a new artist fails to match or best the success of their first release. As we all know, this was not an issue with Madonna. And on November 12, 1984, we all witnessed the now "Material Girls" meteoric rise to superstardom.What was apparent was what was on the horizon. Controversy.Titling an album with the word "Virgin" was pretty gutsy in 1984. And what happened on the very first MTV video music awards had some in shock. But, like it or not, Madonna had found America's "button" and she pushed it with glee.Labeled "An annoying one-hit-wonder, with the voice of Minnie Mouse on helium", Madonna's second album found her branching out to new musical genres. Pop, R&B;, and a first for Madonna, ballads.Selling almost 20 Million copies worldwide, this is Madonna's second album, and a fine example of what was happening musically in 1984.
