Janet Jackson

Janet Jackson released her first self-titled album in 1982 and went on to perform at the Super Bowl and sell-out stadium tours. However, most of her fame is because of her family. Her late brother is Michael Jackson, and you'd better believe the familial connection is what got her foot in the door. 

Kurt Cobain

People have a lot of mixed opinions about the late Nirvana singer. Some say he was the founder of the grunge rock movement, and others say he was a whiny, talentless guitar player who let his career get too politicized. Either way, he's iconic for his untimely death and his musical legacy. Like him or not, he changed the way we hear grunge.
