You raise an interesting point there. To be honest, I have absolutely no idea how music is categorized and classified these days, especially the electronic stuff. Looking at the category selections at DistroKid for instance is like a non-coffee drinker reading the menu at Starbucks.
It used to be easy -- Classical, Jazz, Rock, Country, Funk, Ska, etc... Now it's "Urban Softcore CountryGrunge HalfBeat" or something like that. A lot of NewSpeak type words, and getting too specific IMHO.
