Everything about this song has always said, "Super Villain Theme" for some reason. Cypress Hill, (Rock) Superstar:[YT]W4VpE-0zitU[/YT]
I could see this song being used in an action sequence or even a jailbreak, especially if the one leading the breakout is none other than the Joker. DJ Shadow, Organ Donor: [YT]U4E60Ffa9yQ[/YT]
What better song to sum up Joker and Harley's romance? Cake, Sick of You:[YT]mi9MLL8QOY0[/YT]
