for all intents and purposes, he's only got 2 albums. He's definitely never had a "hit" radio song

but he's collaborated with Hov, Kanye, Beyonce, Tyler...

he has probably the 2 most consensus well-received albums of the last 10 years...

and he may just be the most influential pop musician living today (you obviously can't measure influence, but I'm just going off how everyone else borrows from him)

Frank's one-of-one. He's kind of the mascot for all things cool in the eyes of millenials and Gen-Zers. But he's also, oddly, not mainstream in the conventional sense.
