I'm currently listening to "Hood Politics" and I have to say that the album is really good. As of now, good kid, m.A.A.d city is ahead of To Pimp a Butterfly but still, Kendrick did the damn thing on this album.
I don't want every artist/rapper to release car music and ****. We have the likes of Drake and Big Sean for that. We need a fair share of conscious music/rappers to balance it all out.
To Pimp a Butterfly, 2014 Forest Hills Drive, and Dark Sky Paradise are the best rap albums of 2015 thus far. We'll see where Kanye, JAY Z, Drake (Views From the 6), and co. rank if they release later this year.
