How do you organize your music?

I'm interested to see how others here sort their rock and metal music. I feel a bit conflicted about how some of my playlists are sorted, and thought I might get some ideas from asking here.

Since they're cutoff in the image, my playlists are as follows: Alternative & Pop Rock Black & Death Metal Classic Metal Classic Rock Deathcore & Metalcore Fusion, Math, & Prog Rock Groove, Heavy, & Thrash Metal Grunge & Hard Rock Industrial, Nu Metal, & Rap Rock Post Hardcore & Pink Power & Symphonic Metal Prog Metal (Clean Vocals) Prog Metal (Growls)
