Warner Bros. Records reportedly signed Mac Miller and his independent label for a cool 10 million. As to why Miller made such a move after achieving a significant amount of success on his own; he wanted to explore other options and he was tired of only existing on social media.
I don’t know the details of the deal. But make no mistake about it, when you come explore the options of signing with a major after achieving the kind of independent success Miller has, these relationships become “partnerships” rather than your typical oppressive 360 deal.
