What Kind(s) Of Music Are Headed For Extinction?

I don't think any music will ever be extinct......What might become extinct is the use of genres, categories or "kinds" of music. Disco turned into synth-pop and maybe some rap, rap turned into hip-hop.

I don't see many Baroque-Era composers anymore. So perhaps that style is dying out.

50's style exotica is pretty much dead. There was a brief revival in the nineties, with Combustible Edison and the Ultra-Lounge series, but I think it's over. Too bad, really. I love it to death.

Agreed about beautiful music. And, taking that ahead, old school soul/R&B is more or less gone too.  I must be very much mistaken, but I don't hear too many singers sing in that style anymore. A more breathy, cozy style of singing R&B evolved in the 80s and it's more or less replaced quintessential soul. 

At certain times, I've thought about how, like many things, music styles or genres go through a history of initial rise leading to a period of peak popularity followed by subsequent decline. Then the other day, this question popped into my head. Could any of the music genres or sub-genres that have had some following over the last 50, 75 or even 100 years be headed for total extinction in this century? Now, by extinction, I don't mean reduced to a niche, even if quite small. What I mean is a complete death in the current world. It means no musicians interested in performing the music, nobody interested in writing this kind of music, and no listeners interested in buying or even listening to the music. For obvious reasons, I am limiting this question to music of the Western World. I'm sure there are some obscure tribal musics that are headed for extinction, but that is a debate for the anthropologists. Now, in thinking about this, it seems that practically all of even the very small genres or sub-genres would continue to have at least some following for years to come. Certainly genres like prog or jazz or blues, although they're relatively small parts of today's music world, have a dedicated body of core listeners that will keep them alive for a very long time. One candidate did come to my mind however. I'm not sure what the exact name of this genre was, but in the 1970s (and maybe earlier), it was often called "Beautiful Music". It was largely instrumental with lush strings at it's core, although other instruments and even vocals were often present also, but everything had to be soft and smooth. Any vocals were usually in the background with the other instruments. I think Mantovani was maybe the biggest name in this kind of music. The music had a definite popularity in it's time: I believe that practically every city had at least one radio station entirely devoted to it. I think it was the 1980s when it was completely supplanted by Smooth Jazz (e.g. Kenny G). Today, it seems deader than a doornail. Perhaps there are a small number of older people who still buy and listen to the music. Unlike many small niche categories, it seems to me that there's zero interest in it below a certain age. I highly doubt that anyone's making it anymore either. It sounds like extinction to me. Still, I guess you can never completely rule anything out. After all, who would've foreseen the minor comeback of Gregorian Chant a while back? So anyway, what ideas do you have?
