Lupe Fiasco slams lack of substance in hip hop

Lupe doesn't name names, but says,

"Everything that is Hip Hop from the good, the bad, the ugly, everything else. And I think you got the commercial side of Hip Hop. Everything that you hear on the radio, everything that’s for sale so to speak. And I think that today there’s a very substantial lack of substance in the commercial side of it. Which even affects some of the cultural side of it to because they are one in the same."
