What kind of music do fans of Heroes of Might and Magic like? (music genres)

Wings - yes, undoubtedly. They belong to Catharsis.

Cradle... Well, I won't say much... I haven't listened to them much. And I don't know much about black metal. But even I know that Cradle and Dimmu Borgir are the standards of black metal. That's simply why they are high quality.

Moonspell?

You can hit me over the head, but this is the first time I've heard of them.
Aria... Now we've come to my favorite band. I won't argue with Volkov about Aria being a project for making money. I agree, it is. Only it's been a long time since it was the Aria I love. Aria existed until 1999 (if I'm not mistaken), when the album "Generator of Evil" was released, and then the group split into the new Aria and Kipelov. Neither reaches the old level, when Aria performed songs with meaning, and not this idiocy, like "Armageddon".

Well, in the meantime, I'll write my opinion on the styles Volkov mentioned.
Alt - in my view, it's just a direction in music specifically for people who don't understand the roots and what heavy music should be, but at the same time want to say they listen to heavy stuff and not pop, electronics, or rap.

In general, there is an example. I think those forum members who listen to alternative know the band Slot. Well. This band covered the Aria song "Street of Roses". A legendary song. One of their greatest songs. And what's the result? Dammit, I got the impression that this woman with the microphone shouldn't be singing at all, the instruments should be taken away from those monstrosities and returned to the stores where their wealthy daddies bought them, and in order to sing someone else's song, this damn Slot needs to listen to it first!!!

Nu metal?! What the hell kind of metal is that!? It's a sugary, sickening, disgusting mixture of pop-rock and pop, in which electric guitars just participate and therefore it was called metal, and it was also called that for the same reasons I mentioned about alternative - because it's FASHIONABLE METAL!!! Which is absurd in itself! It's not metal. I honestly don't understand why on earth they took such a name for the style. Typical pop.

Metalcore? Uh... Is that a mixture of rap and heavy stuff? Or am I wrong? I haven't listened to this style. But if I'm not wrong, it's just some kind of perversion - to mix two styles that are opposite in music, lyrics, and philosophy, and after seeing what came of it, to continue performing it! It's sickening to listen to.

Although, I must agree that metal itself is dying out. There are no high-quality, famous bands in Russia now. And abroad, there are only old-timers. Although things are better there. Much better. There are still many strong bands there. I probably spoke too hastily... Metal is dying out in Russia because nobody needs it. R&B, trance, and pop are enough for everyone. And talents? Who needs them? These days it's enough to just have rich parents and grease the producer - a way onto the stage is guaranteed.
There it is - my imho. You can throw minus ratings at me, perhaps I've disappointed some with my opinion, but that's how it is, and it can't be changed. For I consider music to be one of the main spheres of society. And disagreement... Well. It happens that people don't agree in their opinions. Here is my point of view, I hope it is sufficiently structured and justified. If there are any questions, please ask.
