I reworked the page, and took out a number of examples that either didn't fit (due to having no context or not using clips) or were fanvideos someone had snuck in. I'm pretty sure the trope only counts when it's an official video that's tied into the production - we'd be here all day listing fanvids with film clips in them. Deleted examples are as follows:
Beyonce's song "Check On It", which was written for, but ultimately not included on the soundtrack for the 2006 remake of The Pink Panther.
The music videos for the covers on Disneymania are generally this
Anastasia and Ben Moody's song "Everything Burns" has no link in lyrics, concept, theme, or mood to the film Fantastic Four, but that's all the video's about.
This is one of the sloppier examples, since a version of the video exists without any references—direct or thematic—to the Fantastic Four at all, leaving it a perfectly average (if mopey) music video, and making it clear that the song has nothing to do with the movie.
Most of the various music videos cooked up for the songs from Bubblegum Crisis fall under this trope. Most of the footage usually comes from the episode the song appeared in, but clips from other episodes also shows up now and then.
