I get what he's talking about after watching the interview, but Hip-Hop still needs to have the freedom to be all things to all people.
There is however a connection between what Cudi states the mission of his music is and the aspects he believe should be "deaded" but no one in Hip-Hop really has the courage, or gives a fukk enough to connect the dots. Or maybe they feel that doing so would somehow cut off their stream of revenue.
He speaks about loneliness, lack of self worth and suicidal thoughts. Truth be told, a lot of the braggadocio and money talk is rooted in that same lack of self worth. A lot of the disrespect of women is also rooted in lack of self worth or loneliness. So really the only thing different he is doing is giving you his insecurities instead of allowing you the pleasure of discovery through the music.
I think where Cudi has to be careful, and the writer semi-eludes to this in the opening statement, is that there's a line between art and commentary that has to be skillfully walked. The art aspect of the music, for the most part is for the listener to decide, you can't force information onto people through music because then it's propaganda. The listener needs to be able to pull from it whatever they please. For example, Scarface has made numerous songs where he speaks about suicidal thoughts, he doesn't really go in depth about the root cause or how he worked through the issue to create a one-size-fits-all message for the listener rather he respects the narrative and allows the listener to participate in the journey to take what they need from it
