I want to know the answer to the following question:
Which Detroit artist has the highest hip-hop sales?
All the background I'm provided with is that "In the 1990s and the new millennium, the city has produced a number of influential hip hop artists, including Eminem, the hip-hop artist with the highest cumulative sales, hip-hop producer J Dilla, rapper and producer Esham and hip hop duo Insane Clown Posse.". Is that enough to answer the question?
