Man, you can't just contain yourself to one style of music. I'm not trying to imply that you are doing this, however I don't think it's fair to judge this artist on the same scale you would judge an artist making boom-bap raps. Also, one can only listen to so much of the same style, eventually you need to widen your palette. Lean's music, very oddly actually considering the lyrical content and musical structure, feels almost fresh in a system prone to repetitiveness (music/art in general).
