That is if you like music vids... Mine would be Life On Mars. It was the first Bowie vid I saw and I was like Oh My God who is that man? I really liked the way he was made up in that vid, and all those close-ups.And that cool watercolor effect. A close second would have to be Ashes To Ashes because of its weird colours and it overall decadent, alienating feel.And I liked the way he played Major Tom looking all apathetic and bored. The vid really went well with the song IMHO.
