Back in the day when I’d go into a record store looking for Tom Waits albums, later CDs, it was difficult in big stores to find him. On any given album, some songs were experimental, some blues, some spoken word…
I always like message board threads that start “What is your favorite insert genre here band?” By the fifth reply it starts to devolve into the definition of the requested genre and the sub-genres.
So a thread starts: “What’s your favorite punk band?” drifts into “that’s not punk, that’s post-punk” or “new wave”, etc. Just endless bickering what what defines the given genre.
I think it is a mix of hipsterism and group tribalism, desiring to show off expertise and literacy of a genre, though it can be helpful for tracing history and evolution of music across time and culture.
This helpful genre guide has been around forever if you really want to lose yourself…
Yeah, that’s really it. If I tell someone that I want to listen to heavy dub, they know I don’t want light pop reggae. Similarly, if I say I want to listen to stoner/doom metal, they should know I don’t want hair metal if they are familiar with the genre.
The only thing I can think of is that “gap” is also used to refer to a thigh gap. But that wouldn’t make much sense in context here, I wouldn’t think.
But I googled it, just to check. (I tried “mind the gap” obscene). And I found an old language forum post from 2009 where someone said
Last time I was in London I saw somewhere: “Mind the gap unless it’s between the legs of your girlfriend” or something like it.
So I guess maybe she’s only encountered it in that way? Or maybe she just assumed what the OP of that thread asked. Or, heck, maybe someone lied to her about what the phrase meant.
I had the same reaction as the OP, but thinking about it more I could imagine a Jamaican having the same reaction to a flyer that advertised “classic rock, hard rock, heavy metal, and hair metal”. These are distinct styles, but would sound like one genre when played back-to-back; especially by the same band.
Around here cover bands typically advertise the artists they cover more than the genres so the flyers don’t look like a list of variations on ‘rock’ and ‘metal’.
I never knew there was a reggae dubstep. The dubstep I know, and I suspect your kid was talking about, is an especially obnoxious subsubsubgenre of EDM (electronic dance music) that was super popular about that long ago. No clue if it still is. But as much as I love some good dark house (also EDM), dubstep made me want to leave the club.
You could well be right. I can’t confirm, because the only impression it made on me was to suggest what the next generation of elevator music was going to sound like.
