So, I've thought about this several times, and finally feel compelled to share: SCP Theme Music! Yes, I know this is probably a stupid idea, but I can't help thinking of certain SCP items when I hear songs. Some examples:
Able - Indestructible by Disturbed
SCP-293 - Gimme Gimme Gimme covered by A Perfect Circle
SCP-455 - This.
Anyone else do this? What are some of your themes?
