A song of purpose for people of purpose: the 1976 version of the Flamin' Groovies' "Shake Some Action." You'll notice the guitars--how could you not--but make sure to pay attention to the bass. Also: Notice the writing in the comments? See how much this means to people? See how there's emotion and the spark of life in what any of a number of them write? Because it's genuine and real. "So, let me bust out at full speed" indeed. I'm also willing to accept that the greatest moment in the history of recorded sound happens at 2:15. What am I talking about? Listen.
