It might be better to list bands though :D

If you like the more louder music sung by a woman:

The singer from Nightwish Floor Janssen started out with "After Forever" (Dutch band) and that was one heck of a band.

"The Gathering" (Belgium) has an amazing EP: Nighttime Birds Click here to play one of the songs (but it is one of those albums you need to listen from start to end). https://mp3-128.jango.com/music/06/60/23/0660235554.mp3 "On Most Surfaces". Whole album is dopamine for the brain.

Oh another amazing one from the Netherlands: Ambeon (also a Dutch "band"). 1 EP called "fate of the dreamer" if you can find it. Ambient music but with a gothic metal kick. Sung bu a young girl with a voice.
