There are tons of mood vidders out there, though they may not self-identify that way.

I recommend taking a look at buffyann's work, particularly Dreams (http://buffyann.livejournal.com/26915.html), to get a sense of it. lim's work also does a lot of lyric vids.

I've been leaning heavily toward thesis-driven vidding for several years now, although I can't seem to vid completely non-narratively no matter what I do!
