I for one agree with you. There are some hip-hop artists, some of whose tunes seem interesting and deep. But I am turned off by the braggadocio, weed shoutouts, and the tendency to simply rap about rapping found in these artists' work and across the genre in general.

In searching for hip-hop without braggadocio etc., I have repeatedly been told by hip-hop aficionados that these tropes are inherent to the genre and it would be unreasonable to seek hip-hop without them, just like oldies rock was inherently about dancing or sweethearts, and country music about personal woes and drink.

It is a shame, because the genre seems to have the potential for more lyrically. Hip hop is now a global phenomenon with innumerable performers. Is there really no hip-hop out there with a more abstract lyrical approach, like for example Climate of Hunter-era Scott Walker?
