Thanks for your input. I'll ask Robert Baird about this.

Rocking it flamenco hip-hop style in Vegas,

I was thinking the same thing. Reggae, Dub, electronica, IDM, EBM, Industrial, Free Jazz, Folk, Thrash, Country, Dance, World, Grime, Dubstep, Drone, Alternative, Trance, Bebop, Instrumental, movie score, Opera, Classical (chamber, period, composer, period), Avante-Garde, Noise, Field Recordings, Spoken Word, Audiobook, Hip Hop, Disco, Indie, Brass Bands, Live, Rap, Death Metal, Concert...list goes on and on.

There are probably 100 or more different genres, if one wants to get really specific.

Stereophile obviously chooses to use its limited space for those that are of interest to the most readers, such as classical and jazz, and generally, pop music. Maybe they need an "Other" category to encompass anything else of interest not otherwise covered.

I am sure that there are specialty music magazines for various special music interests.

Geez...and for old farts like me there is no "Easy Listening". LOL
