18. NOTORIOUS B.I.G.
Few rappers have influenced rap music as much as the Notorious B.I.G., but he grew up very poor. His poor upbringing led him and his friends to look for a way to make the cash they saw everyone else with. They started selling cocaine. He was eventually arrested and put in jail for nine months. He never got a real chance to turn his life around, because he was murdered at 24.
