Kanye West.
Hate on him all you want, but every solo album he's released has been critically acclaimed and commercially successful, in addition to being hugely influential. My Beautiful Dark Twisted Fantasy especially stands out as perhaps one of the greatest mainstream albums of the 2010's (so far).
Between the quality of his music and his usually bizarre public persona, Kanye's definitely going to be remembered as a classic for a long time.
Also, Beyonce. But that hardly needs explaining.
