Butterbeer Experience- The Prince's Tale
So, this is definitely my favorite song by The Butterbeer Experience, and however cheesy this fan-made video is, I love it.
I think this song perfectly sums up the Prince's Tale- from both Lily and Severus's point of view. The first time I heard it, I broke down and cried. The next few times, I still cried. Eventually I got used to it, but I still get sad whenever I listen to it.
But this video doesn't have the entire song, and you HAVE to listen to the entire song. It's not on Youtube, but you can listen to it here, on Bandcamp: http://lenagabrielle.bandcamp.com/track/the-princes-tale
Oh, and Christian Caldera of Oliver Boyd and the Remembralls sings Severus's part. God, I love his voice.
