Do all rappers have made up names?

Not all rappers have made-up names, many rappers use their real name or a variation thereof. For example, Eminem's real name is Marshall Mathers, and he sometimes uses his real name in his music. Other rappers, like Snoop Dogg, use a stage name that is different from their real name, but it is not made up. Snoop Dogg's real name is Calvin Cordozar Broadus, Jr. Some rappers do use made-up names, however. For example, the rapper 50 Cent's real name is Curtis James Jackson III.
