Geffen records has been one of the most successful and lucrative record labels in history and has contributed largely to David Geffen's personal net worth of $5.1 billion. Without Geffen records, there would be no Dr. Dre, Eminem, 50 Cent, Ludacris, Mos Def... thousands more. Geffen would go on to make a fortune in the film business as part of Dreamworks but his contribution to music and hip hop will always define him.
