He just did a $10 million deal with Warner despite already being one of the most successful independent rap artists ever. There's no way he's not being angled as a mega-pop star. As to his long-term odds, I couldn't call it. But it will say a lot about the direction of hip-hop going forward. He doesn't have the world's most distinctive style, but how much will that matter in 2015? If Macklemore was the breakout star of 2013, and Iggy Azalea was the breakout star of 2014, could Mac Miller reach their heights in 2015?
