I really love the song Everything is Embarrassing by Sky Ferreira. It's heart-wrenching with a hypnotizing rhythm. My favorite line is the opening line of the song "everything and nothing always haunts me". I think a lot of us can relate to this kind of love. A love you tried hard to hold onto when you knew it wasn't right for one or both involved.
