Rapper Common, born Lonnie Lynn Jr started rapping in high school with 2 of his friends and were so good they actually opened for Big Daddy Kane and N.W.A. He later chose to go solo under the name Common Sense but as he got older, he thought rap had sold out and made a point to make positive, insightful lyrics. But a dis in one of his tracks led to a feud with Ice Cube, and then a lawsuit.
