I was relatively late to watching Community, but... it's awesome. Way too awesome to be successful. I still can't decide if mainstreamification is a worse fate than death, and what do I do when I'm indecisive? Make a song! Also eat a lot. Oh, and because of the immediacy of the inspiration, I know that this is pretty crap, especially the performance.
Oh, and the beat is taken from "Greendale is Where I Belong," by the always incredible Ludwig Göransson.
