I am usually not one for music video's and think that for the most part they end up detracting from the song, but every once in a while someone sends me one that blows me away.  The best ones bring out the song without overpowering the music, which is easier said then done.  LCD Soundsystem's video for New York I Love You But Your Bringing Me Down is fantastic!  It is done in just a few simple shots with a hand held video camera and a puppet, but the effect is beautiful and poignant.
