This is kinda interesting. Here's a few random Youtube videos that I've found that feature music I've written, that I totally didn't post...
http://www.youtube.com/watch?v=pAXMhwE9NQYOur Turd Ferguson classic "Alan Cumming" set to pictures of the man himself. (4800 views. Nice.)
http://www.youtube.com/watch?v=HEOO_fG51iUAn anime set to "M (Alter Ego Remix)".
http://www.youtube.com/watch?v=q6tzV8IKxwgClips of Dr. Who doing his regeneration thing to the song "Regenerate". (2500 views?!)
http://www.youtube.com/watch?v=0ZelA4OXHhkClips of an anime that features a car driving around set to "Coming Clean". (1600 views!)
http://www.youtube.com/watch?v=L7pIapdocZoSomeone posted "Awake" with an old picture of me static, but it still has 1000 views in 4 months?!
http://www.youtube.com/watch?v=QqDeH2snRq0Some grad school folks making some kind of video set to "This Is Your Crappy Christmas Present".
http://www.youtube.com/watch?v=qwE7S0DwjVE"Alone (Ich Liebe Deutschland Mix)" with just a static compilation album cover picture.
http://www.youtube.com/watch?v=MLcTbSXuXdwThis might be the weirdest choice... my 1994 song "The Vision" (easily one of my worst very early songs) set to static shots of 3D character models.
