I enjoy listening to a song and associating it with a person I know.
For example with the Joker, one of my all-time favourite characters/villains.
Do you know any songs that instantly remind you of him? I would love to look them up!
My own list is short right now, I hope it will change with your help:
• Wrong - Depeche Mode
• Corrupt - Depeche Mode
• I Want It All - Depeche Mode
[Joker mostly on Harley Quinn]
• Crazy (Gnarls Barkley Cover) - Violent Femmes
• Undisclosed Desires - Muse
[Harley thinking about Joker]
• Meds - Placebo
[particularly reminds me of the process while he was slowly becoming the Joker (and scared of it)]
• Burn - Nine Inch Nails
• Agent Of Chaos - Mr. Rey (on YouTube)
