The Diamond Sea and Mote are two of my favourite. I hate the Addicted To Love video, but love the song really much... :)
'It's closer to the truth to say you can't get enough..."
Oh yeah.

Nobody mentioned Drunken Butterfly?!?! I love that video! It's my second (maybe third) favorite (behind Shadow of a Doubt and Macbeth/Mildred Pierce)

Also in the lofi category:
Death Valley '69/Scooter & Jinx (I'm grouping them together cuz they're both by Richard Kern)
Tunic
Mote

in the mid-fi:
Hoarfrost
Sugar Kane

in the hi-fi:
Little Trouble Girl
Sunday
Bull in the Heather
Kool Thing

I really love the Diamond Sea video. All the live footage put together with the song, it's just awesome. I also really like the Sunday video.
