Looking for some hauntingly beautiful songs.

So as the title says, I am looking for some songs that are hauntingly beautiful, songs that are tranquil, and will probably stick with me for a while. They do not have to be of any particular genre' and remixes or covers are more than welcome.

Some songs that fit this description for me (and might give you a better idea of what I want are:

Mad world by Gary Jules

Bill and Annie by Chuck Brodsky

Closer by The Tiny

Too Much Time by John Vanderslice

Walk Through Hell by Say Anything

Your Song by Ellie Goulding

Edit:whoa...just woke up and saw all the new responses. I'm sorry I don't have time to go through it all tonight, but I promise I will make a spotify play list and listen to all of these over the next day or two. I'll try to get back to as many of you as I can, and thank you so much for all of these awesome suggestions!

Edit 2: I'm sorry guys. There's just too many submissions, and I have too little time. I've made a playlist on spotify of everything that I can, I will get back to this in a week when I will have more time. for those of you interested Here is the spotify playlist. The Playlist name is "Reddit's Hauntingly Beautiful Songs" by the user Trajedie
