The single's only the look to sell these niggas the book
I can only pray that one day you’ll read into it
J Cole has radio songs but that is just to please the masses and get air play. He means that a single is the equivalent to a book cover, because its all you see at first. As the saying goes, don’t just a book by its cover.
Cole is saying those types of singles are meant to get people to buy the CD — of course an artist wants you to buy it — and he hopes that single leads you to listening to the rest of the album, and possibly his music period.
He’s also saying read into the deeper meaning of the music, he’s dropping gems and knowledge he hopes someone would catch.
