Here we have the scene in First Born in which Dean and Crowley convince Tara to show them how to locate Cain and the First Blade.
First off: It’s a pawn shop. No symbolism there, right?
And then take a look at the items that are displayed. It’s a pawn shop which sells:



1) drums, guitars, banjos, stereo equipment, tape decks, speakers, headphones, horns, and golden records
2) watches, rings, necklaces, and shirts/jackets
So here we have on one scene: a place in which people sell things that are precious to them in a time of desperation, in exchange for things to wear, and in which there is everything you need to play music.

Crowley’s greatest hits, indeed.
