|What's wrong with mass market?
Bose made the best, sold a lot, and now have money for even better stuff, R&D, etc.
Well, in theory.
It may also be a case of you pay for the brand because they had the best marketing
Black Sabbath certainly isn't black metal, although it's been a huge influence on it (and on all metal genres, specifically doom metal).
Black metal is more raw and extreme, traditionally lo-fi and dealing with topics such as Satanism, death and misantrophy.
Mayhem's 1994 De Mysteriis Dom Sathanas is still considered to be one of the best, and the prototypical, black metal album ever: Mayhem - Freezing Moon[^]
Of course black metal evolved and there are now plenty of sub genres.
One of my favorite black metal band of the past seven years or so is Oranssi Pazuzu, who play a more psychedelic kind of black metal: Oranssi Pazuzu - Uusi teknokratia[^]
The same goes for death metal, the two are closely related.
Just compare Morbid Angel's classic God of Emptiness[^] to the latest release of At The Gates[^].
Both are death metal, but they sound pretty different (to the trained ear at least, most people can't get past their expectation of metal being a wall of noise).
When talking about "dance" I mean the electronic kind.
Just turn on a popular radio channel and you'll hear some dance music, at least in Europe, artists like Avicii (RIP), Calvin Harris, Dua Lipa...
Again, lots of different kinds of dance music.
In fact, trance is a sub genre of dance, since you dance to trance.
Other sub genres include drum n bass, (deep) house, techno... (and I listen to most of them, though not as much as I listen to metal).
Here's some Avicii: Avicii - Wake Me Up[^]
And here's some trance (of my favorite kind, psychedelic trance, or psytrance): Infected Mushroom - Dracul[^]
And a techno favorite of mine, just so you can hear how different the genres really are: KAS:ST - Hell On Earth[^]
Who the heck listens to muzak and where do you even hear that stuff?
"Muzak is an American brand of background music played in retail stores and other public establishments." Ah, alright, I'm in Europe
I can certainly get into it though!
I make it kind of a thing to know and listen to many different genres of music.
As said, I also enjoy classical music, mostly the baroque and romantic periods though, especially the national romantic period with composers such as Grieg, Dvořák and Sibelius, love the traditional folk influence.
