i hesitate to say ever, but the video for Hungry Child by Hot Chip tends to be the one that i show up with when this question comes up. more diegetic music videos please 
i got a hankering to listen to Bath Full of Ecstasy this morning and this is still such a music video targeting my specific bullshit and i love it so much forever
I would post the one with the astronaut that goes into space as the world blows up but I think that got taken down some years back :(
so instead I'll say this even though it isn't official
Here's a few real fun ones~! I lost my original of just links (like half of them are dead anyways so start over) and I got some gems
Pharrell Williams - Cash In Cash Out
This song is like four separate songs all fighting each other but the idea of actually animating a zoetrope in action is genius

Cassius - Go Up
Legit surprised we didn't see a ton of this kind of music video, it's so cheap and effective ! ! I'm also biased on the jams cause I'm a forever a french electro-vibe apologist

Salvatore Ganacci - Fight Dirty
Salvatore's whole vibe is extremely good imo, and this animated video is a highlight as well as a fuckin BOP

Yasutaka Nakata - Crazy Crazy (feat. Charli XCX & Kyary Pamyu Pamyu
