Have you heard of "Conscious Rap"? It's the practice of creating rap music around the topics one wants to be educated, and then listening to it ambiently. That subgenre has many tendrils, as people with unrealized lyric talent make raps about politics, finance, how to maintain, and developing critical thinking skills and then in the Conscious Rap social media sharing sites their personal music takes off.
I like going to BandCamp.com and they have a Conscious Rap section, in that section you find all kinds of interesting music. Each band/mc has their own band page, and on those pages they list other sites they can be found and those listings are gold. Tiny little online labels, or just lone artists, and some are not really music artists at all, more like collage audio philosophers.
