I'm asking this becase Bolero Effect is on the "Examples Need Sorting" list, and all of the examples on that page would be sorted into what ATT currently calls "Music".
If yes, Wikipedia uses these broad categories, which I propose using as well:
- Blues
- Brass & Military
- Children's
- Classical and Opera
- Country (including bluegrass and western)
- Electronic
- Folk and Traditional
- Hip hop
- Jazz
- Latin
- Pop
- Reggae
- Religious
- Rock (including metal, punk, and classic)
- Rhythm and Blues (including funk and soul)
- Stage & Screen (including music-hall and soundtrack)
