For me it will always be A-Ha's "Take On Me", though basically any of OK Go's videos also deserve consideration for sheer creativity.

Jamiroquai - Virtual Insanity

Smack My Bitch Up - Prodigy (the full, uncensored version)

Don't really have a fave but here are some I enjoy:

Muse - Knights of Cydonia

C2C - Delta

Miike Snow - My Trigger

Childish Gambino - This is America

Michael Jackson - Thriller

DJ Snake, Lil Jon - Turn Down for What

Phil Collins Peter Gabriel, Sledgehammer

Whoops

The Wall, obviously.

Alright, that's probably cheating, so let's go with Colorblind by Elliot The Bull

Or literally anything by OK GO.

Edit: Scratch all of the above, it's Weapon of Choice by Fatboy Slim.

Personally, most of the stand-outs that come to mind are all OK Go music videos, since they still incorporate the music, but also feature videos that are creative and engaging in their own right. Of theirs' I'd say I Won't Let You Down is the best, but I personally prefer Obsession.

Aphex Twin - Windowlicker

I think most of their music videos are pretty good, but I've always liked this one the most I think.

Electric Callboy - We Got The Moves

Hot Chip - I Feel Better

Amazing song and the video is just wild. Boy band lead singer blasting people with mouth lasers

Thriller -Michael Jackson.

Uncontacted tribes in the Amazon know how to do the Thriller dance.

And why is it Windowlicker?

Agreed with others that there is no “best.”

That said, Sledgehammer by Peter Gabriel was incredibly inventive: https://youtu.be/OJWJE0x7T4Q?is=KD8iB_CjSs2-PII-

As was Jamiroquai-Virtual Insanity: https://youtu.be/4JkIs37a2JE?is=ATzpLv2HAtLVNBiW

And I can’t find it but the original video for Shadrach by the Beastie Boys took a live performance film and then rotoscoped it with impressionistic (expressionistic? I’m not an art historian) brush strokes that somehow just fit the music.

Metallica - One

Sports - Viagra Boys

I heard this on the radio at work near when it released and I laughed so hard that I had to walk into the back. Completely forgot about it then found it organically youtube a few years ago and had the same reaction. Is it the best? Well, no. But it is a unique experience.

I know OP and multiple commenters already said OkGo, but these songs/videos have been a micro obsession of mine the past week and I can't pass up the chance to share them

For this one, the entire song is played via percussive methods by driving a car on a prepared track with improvised instruments. Damian, the lead singer, had to learn stunt driving to drive the car at specific speeds for different parts of the track. They calculated the spacing of instruments over the distance as well as how much time it would take to maneuver to different parts of the course and the speeds necessary to maintain the correct beats per minute. They used over 280 guitars and 55 pianos, and modified the car with audio equipment and levers to control what mallets were extended. The song ends up sounding rough, frustrated, desperate and pained which is perfect for the lyrics, and IMO better than the studio version.

The other one is Upside Down and Inside Out. The song alone is not my cup of tea, and yet with this video it's really incredible. They recorded the video in 27 second increments of parabolic flight to make the whole thing happen while they're weightless. In the times between takes, they had to endure 30 seconds of 2x gravity and then wait 5-10 minutes to climb again. The sequences are edited together, so if any of them didn't make it back to their marks in time the take wasn't usable. They spent two weeks messing around experimenting with choreography and props, and one week filming.

They do making of's on a lot of their videos, and it's truly incredible the amount of time and planning and preparation and ambition they have for them.

C'mon. It's fucking October. It has to be Thriller.

The Chemical Brothers - Let Forever Be

Weezer - Pork and Beans

When it first came out it was a distillation of a bunch of cool stuff on this Youtube thing. Now it's a time capsule of nostalgia for a time when creativity ruled. Plus it's one of my favorite Weezer songs.

Let's see, there was that Meatloaf video where he was dressed up as like a lion man or something.

That one was pretty cool.

And of course there's Thriller, which is probably legitimately the correct answer.

De Staat - Witch doctor

• The video clip allways weirds me out but I'll never stop watching when it's on.

Fatboy Slim - Weapon of choice

• Christopher Walken kills it.

The prodigy - Smack my removed up

• child sentiment. Love the POV style.

Aphex twin also gets a solid place in my heart. Love all of their videos

Window Licker

Come to daddy

The Presidents of the United States of America - Peaches

It's still the video to "all is full of love" by Björk for me. I found the style and pacing so intriguing that I heavily copied it for a computer animation I did at University.

“I'm really happy for you, I'mma let you finish, but Beyoncé had one of the best videos of all time!"

Birth of crabcore, baby!

Attack Attack - Stick Stickly

Pendulum - Slam

Just saying. Theres no real laws against this. Nobody will actually stop you.

Disturbed - Land of Confusion

Genesis - Land of Confusion

Foo Fighters - Learn to Fly

Rush - The Big Money

This song was surprisingly wholesome:

The Northern Boys - Give It to Me
