My favorite one is GPASUYF.. the only one with a plot. I think it shows how easily one can lose themselves and blend in with the masses (or disappear), if you become too caught up in yourself and your own things. Fecking amazing! And Chris pulls some great moves in it.. and OMG Jonny's hot mustache! :cheesy:
Other favs are Don't Panic, very artistic. Shiver for its simplicity. Both Troubles, though I prefer the UK version because it's bit more serious and real. The Scientist of course, it's very well put together.
The only non-fav I can think of is The Hardest Part. It's growing on me, but I know I'll never really "love" that video.
