For the most part, I think music videos suck ass. 90% of them are formulaic and blur together into a wash of boring images that don't enhance the song at all, 9% of the remainder are only good because they have hot babes in them, and only the final 1% seem to have any kind of vision. But every once in a while, an amazing video comes along that makes you glad you bothered to watch... the first one I remember doing that was a-ha's landmark video for Take On Me. Others have come and gone, but now I've run across this really cool retro video for Junior Senior's Move Your Feet.
The above screenshots don't really do the video justice, because it's the movement that makes it so cool... kind of like an old Atari 2600 video game or something. Worth a YouTube search to take a look.
