Pharrell Williams - Happy: Trombone Loop

IMHO, this is Operational Intelligence (OPINT) set to music and looped into the Commander's Intelligence Cycle—every sound, every note, every beat is like a piece of information feeding the battle rhythm to serve an intelligence requirement. It's waste in the information space if it doesn't satisfy the Commander's Critical Information Requirements (CCIR) or make them HAPPY—https://www.youtube.com/watch?v=ZxODzxY6AvI

WARNING: Very Addictive. Take in small doses.
