Hm... do they have a way to automatically do this to any song?

Yes: you can use Echo Nest Remix in python or do what paul did and pre-load the analysis and do the playback via webaudio. Remix takes care of the chopping at the right bits for you: http://echonest.github.com/remix/

This is really awesome. They cut the entire song into one-beat segments of sound and video, and then categorized each beat by similarity to other beats in the song, and then after each beat there's a random chance that, instead of playing the next beat, the playback will transition to a different but similar-sounding beat from elsewhere in the song.

such a simple concept resulting in nearly endless fun :)

My favourite thing about this is that you can basically make your own remix by clicking about the squares below, and you get an amusing chopped up video for free.

This is a very clever hack and I adore it for that, but it's also a sneaky statement about meaning, and I adore that too. It's like the literature world's cut-up/exquisite corpse work: if you can disassemble an original like this and put it back together in a way that we humans are inclined to extract meaning from, does that change the meaning that you perceive in the original work?

This is fantastic. Steve Reich would be proud.

That might just be the first time Steve Reich has been mentioned in relation to Gangnam Style!

ps To the author/s (if you end up seeing this): was there a reason you didn't center the content on the page? Might look a little better. Just a suggestion :)

Done with bigger squares and optimized for a tablet, this would be a compelling UI for a live DJ performance.

This is how Ableton Live works (and Renoise introduced a similar live view a while ago), although of course it doesn't take any random audio file but rather your own compositions, written in Ableton.

Madlibs for music. Peter Langston, whom I met at Sun while he was consulting on the *7 project, did an interesting paper in infinite music [1]. We built something akin to the Casio "smart beats" feature from their all-in-one keyboard products into the application so that we'd always have musical accompaniment in the UI. Of course that was before we realized that many (most?) people insanely hate UIs that make ambient noise :-)

The Echonest stuff, done over the selected works of an artist could make for some interesting mashups of their work.

Infinite Gangnam Style - Frequently Asked Questions

What is this?

- Infinite Gangnam Style is a web app that dynamically generates an ever changing and never ending version of the song 'Gangnam Style' by Psy.

It never stops?

- That's right. It will play forever.

How does it work?

- We use the Echo Nest analyzer to break the song into beats. We play the song beat by beat, but at every beat there's a chance that we will jump to a different part of song that happens to sound very similar to the current beat. For beat similarity we look at pitch, timbre, loudness, duration and the position of the beat within a bar.

How come this doesn't work in my browser?

The app requires the web audio APIs which are currently best supported in Chrome and Safari

What does Psy think about this?

I don't know. I hope he doesn't mind that we are using his music and images. We hope you check out his official video and his web site too (but really you probably already have).

Who made this?
