Fanvids are dead? I have been watching them for a while. Like you said they are great ways to find new songs so on youtube at work I often pick a character from Marvel and type fanvid and just see what what came up.

I did notice a lot of the legacy ones got pulled, which is a shame. Which reminds me, at SOME POINT, I need to watch the ones from Escapade Con (and need to go back to it some day).

Soundtracks I kinda get in that it is fun to see what music other people think relate to me favorite character, but in the end, it is more or less song rec.

Though when I had the time to write fic, I found them useful.
