I don't avoid any genres. But I've still found songs I really like from genres I haven't explored very much yet, either because they're unusual/rare to find recordings of, or I haven't had time.
examples:
Soca (Caribbean genre i haven't explored enough)

Girl Group (i'm not very into this genre but this song goes above and beyond)

Gospel from Ghana (it sounds very different from usual Gospel)

Vaporwave (i'm well-acquainted with the genre, but this is the only release i love)

Balkan Brass Band (even though they're Japanese)

Southern Soul (haven't found a soul song that i like nearly as much as this one, well maybe one but whatever)

Southeast Asian Classical Music (need to get more into this, i'm amazed at how some sounds like American Primitivism)
