Cover art for Joy lyrics by Ellie Goulding

One of my favorites! To me this is about what started out as a great relationship with that "high i get from you" Then she gets caught up in it. The relationship goes bad. And she's realizing that she is happier without him , though she'll always miss him. She has to leave because she realizes it is not working anymore.
I love how inspirational and hopeful this song is--even though it's about a break up.
