What is your favorite Stevie Wonder song?

Do you know what the mark of a truly great artist is? When you routinely find yourself changing your mind when it comes to pinpointing what exactly your favorite song by that artist is - its an indecisiveness in my life usually reserved for the types of deviant pornography I finally decide to "rub one out" to before starting my day. When I stumbled upon this 1975 grammy performance where he delivers a rather infectious "You haven't done nothing" - it automatically moved "As" out of my top spot, even though the hook on "Too High" is a force to be reckoned with, thus making it a rather formidable opponent in the weeks to come. Stevie Wonder is hands down my favorite artist of all time, and despite his 40 years worth of blessing all of us with ear-pleasing melodious mission statements of Love and Hope - his musical brilliance is to blame for my intolerance of subpar artistry. Being a fan of a man whose work ethic and perfectionism is second to none, who has a "go big or go home" aspect to creating songs - every time I hear an MC give a less than spirited 16 bars, I sincerely want he/she to euthanize themselves with an extremely dull butter-knife. Every time I hear Missy Elliot come out the same fucking song year after year, it makes me ashamed that I hail from the same state that she does - and that's saying a lot, with Pat Robertson being my neighbor and all. Even though black men are an endangered species, when my ear openings are breached by these minstrel show rappers that only appeal to black folks who I would immediately give up if I was ever captured in a race war - I want all of those motherfuckers to miraculously disappear, Jimmy Hoffa style. Stevie, YOU did this to me!!!
