So we should take his idiotic music as something of value because "Hate Being Sober" and "I Don't Like" are not terrible rap songs, but rather art pieces showing what the real Chicago is like? Come on.
I stand by my opinion that his music has no value. It's music that glorifies the absolute worst things plaguing the Chicago area and only goes to reinforce that killing is perfectly fine, can get you a record deal and millions of Youtube views. It reminds me of when Kendrick Lamar was asked what he was writing when he was 16 and he said it was a bunch of terrible murder music. That's what this is, minus any insight, intellect or wit.
You're acting like it's his fault. He's an 18 year old who grew up in one of the worst areas of the country. Your assertion that those songs are "Terrible" is subjective, and would be argued by many. It's probably useless to do so, but my point is that you seem to think that in order to be valuable, music must be some kind of critique or commentary if it arises from a pit like the area of Chicago that Keef is from. He's an victim - his music is, whether you like the way it sounds or not, the music of a culture. To dismiss it out of hand because it doesn't play into your expectations and standards is ludicrous. If anything, the vapidity and violence of the music should be of intense interest to someone who's concerned about the deteriorating state of the city as it's a pretty alarming statement from a young kid.
Insight, intellect or wit - the kid is 18. Barely older than Kendrick was in that statement. Locking him up because his music is "terrible" to you will prevent him from even having the opportunity to grow. It might seem unlikely, but maybe Chief Keef will mature and become the greatest voice for reform in Chicago.
If you're so desperate to have value from your music, the value of this music can be as a tool to show people how deplorable Chicago's violence problem is.
