Reply to EDM sub-genre's seem redundant

Anyone else believe this?

It seems like in EDM, someone will try to "coin" a new sub-genre with any little variation.

For instance, how many different kinds of house are there (rhetorical)?

Look at "alternative" for instance, it covers so many different sounds, and so many different styles, but it seems like within just the genre of house alone, anytime someone introduces a slightly different sound, they have to "coin" a new genre. And on that note, the term "alternative" was once a genre to describe something that was different from everything else. Now it's one of the most commercial genre's out there.

I remember back in the day, people I knew started using the term "progressive drum n bass" and where is it now?

For the sake of my own sanity (and for the sake of my music library) I've tried to keep the genre classification as minimal as possible.

It also seems like a way to express elitism as in "that's not minimal techno, that's microhouse".

I remember asking someone what the different was between "techno" and "tech-house", and one guy said "it's house, but with a techno sound", to which I replied, "if it has a techno sound, is it not techno?" The response was "no, it's house".

"But what makes it house and not techno?"

*blank stare*

Not to mention, I just read in a thread yesterday that there's a music purchasing site that has the genre "romantic techno".

Is this worthy of a facepalm or am I totally off?
