Never heard of it either, but Hozier's song, "Cherry Wine," will have you crying like a baby. As will Lord Huron's "The night we met,"

Listen to it guys, it’ll give you better understanding while I check out your suggestions

I don’t YouTube in my area, so I just saw the lyrics instead, it looks like you aren’t into the romantic-ish feels, but the war-ish feels

Oh wow, that's actually really good!!

In that case I’ll recommened Senbonsakura, even if it’s completely feels

*not completely feels

It’s also the way they sing, sorry it’s not available to you. “Could Be used to light the dark” is a really cool part of it

Children of the elder God by old gods of asgard

@skyliemarie Hozier is amazing

And wanna feel things?
Watch the video Trilogy of The Lumineers new album Cleopetra.
Murder Song by Aurora

Battle Cry by Imagine Dragons for the war-ish feelings

Let It Go by James Bay

Nobody Knows by The Lumineers

Mockingbird, When I am Gone by Eminem

Wish It Was True by The White Buffalo

Honestly try the ballad version of any song for it to be depressing

For most of them yes.

I will listen when I have the time

Boomtown Rats - I dont like mondays

Seconding both of @skylermarie 's suggestions and adding on Elliot Moss's "Without the Lights" if you want dark feels.
