Are there songs that particularly remind you of any of the link characters? Demona? Macbeth? The Weird Sisters? Here are some of mine:
Behind these Hazel Eyes (Kelly Clarkson)
I'm With You (Avril Lavigne)
Who's Gonna Ride These Wild Horses (U2)
The music from the show, especially when Wyvern is under attack in season 1 and in City of Stone (season 2)
Bet on It (High School Musical, don't judge, lol)
Any others you can think of?
