I always skip songs, but my least favorite song of nearly any song on my Ipod happens to be from one of my favorite shows-- Dog Eats Dog from Les Mis. Even when I saw the show for the first time, I kind of zoned out and was like "ooh pretty lights, bad song" during that scene.
Cosette: Roses are red.
Marius: Violets are blue.
Eponine: You're so in love!
Marius: And so not with you.
