Do my favorite artists have something unique to say?

My personal top English-language albums, by the variety and uniqueness of their lyrics. Albums with more variety repeat themselves less; albums with more uniqueness repeat other artists less.

Larger symbols mean more total lyrics in the album; hip-hop albums are diamond shaped. I also listen to a lot of music in French, but excluded those artists here.
