I will!
Metallica for a dark, thoughtful mood
Dragonforce for fun, energetic, silly moods
Mick Gordon’s DOOM soundtrack when working out
Avenged Sevenfold for a carefree, fuck the world attitude
Blind Guardian when I’m looking for high fantasy, “take me away” mood
Sabaton when I want some motivation for work
Rhapsody of Fire for when I’m cleaning alone and want to get into some classical feeling stuff
Killswitch Engage when I’m feeling edgy
Korpiklaani when I’m wanting to go on a run
Parkway Drive when I’m angry or sad
There’s so many more than this, and much of these have overlap with specific songs instead of general artists, but this gets the point across, I think
So, this is gonna sound weird, but I actually find a lot of these bands calming to listen to. I’m autistic, and have a lot of weird sensory issues because of it, so music that’s too simple (a lot of pop or punk or other genres that show up on the radio usually) doesn’t fully grab my attention. Like, there’s not enough happening at once for me to feel immersed in it.
So I’ll end up listening to Power Metal to fall asleep sometimes because I can hear every instrument individually, and my brain switches focus to each one at random times, and it’s stimulating enough that I can be completely distracted from my other senses and calm down. Dragonforce is my go-to because they even have two lead guitarists at the same time.
That said, I do have songs of every genre in my library, and if I do want something slower or simpler, there’s a ton of Metal ballads that aren’t necessarily high energy. Try something like Crimson Day by Avenged Sevenfold, Remembrance Day or Trail of Broken Hearts by Dragonforce, Christmas Truce by Sabaton, or Mother Gaia by Stradivarius.
There’s a lot more examples, but you can certainly have slow, calm metal. I could probably make a decent sized playlist
