"EMINENCE FRONT" - The Who

This is my favorite song by The Who. The build up in the beginning is epic, and you just cant help but nod your head and let the rhythm float you away. This song gives me motivation to get up and do work. I constantly listen to it before tests, etc... To me, I imagine it serving as an entrance theme for a fighter, or something along those lines. It just puts you in that mindset to get shit done. Its also in the movie "Law Abiding Citizen" and plays right before he murders his cellmate.
