From what I can tell, the color indicates the number of beats in the jump set. Black: 1, Blue: 2, and then more the redder it gets.
I can't figure out how to get out of that mode, though, other than to stop and restart it.
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 :)
does the trick.
Yep, it would be interesting to read about things we miss - lyrics, and meaning of obvious references we don't get. For example, I think that dude in the elevator is an actor I saw in some movie, but I don't know if I'm correct. Obviously scene in sauna has some humorous meaning, but, again without lyrics it's unclear.
c'est la vie.
There are lots of cultural memes in America that aren't in English. You can restrict to "recent pop culture", but even in straight music, 99 luftballoons was big 25 years ago. I'm sure there are many other examples.
Edit: I guess I'm wrong:
Having achieved widespread success in Europe and Japan, plans were made for the band to take the song international with an English version by Kevin McAlea, titled "99 Red Balloons". The English version is not a direct translation of the German and contains a somewhat different set of lyrics. The later-released English translation, "99 Red Balloons," was the version that became popular outside of Germany and neighboring countries, with it topping the charts in Canada, the UK, Australia and Ireland. Interestingly, it was the original German version that American audiences preferred, becoming the highest Billboard charting German song in US History, when it peaked at #2 in the US. 
At the end of the day, lyrics are a much smaller part of the musical experience than people give them credit for.
Then again, I have a very easy time dissociating lyrics (and their meaning) from the rest of the music, so maybe that's just me. This doesn't always happen, but it's not unusual for me to listen to a song enough times to internalize the syllables and sing along, and still not stop and think about what the words actually mean (even in English). It may sound odd at first, but when you think about it, you probably have the same experience when you go to the opera - try and make out the words of Handel's "The Messiah", an English opera, and you'll see what I mean!
(And now that I think about it, how many people know what the verses of 'Born in the USA' are really about?)
Also, I did already know that the German version was more popular, so it's hard to be sure I'm not just rationalizing that knowledge after-the-fact! :-)
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?

The crystal theme worked the best (it's basically some scales on the piano that go up and down).
With a first order Markov chain, the output was a random walk of notes going higher and lower. With a second order chain, the notes went up and down fairly steadily, but with scales peaking at odd points. With a third-order chain, you get close to the original song out.
(It's hard to explain in text, without knowing the correct music vocabulary, but I hope you get the idea).
Actually, I think this kind of Markov model might be a better introduction than some of the others I've seen, since it's extremely simple to understand.
I don't know his music well enough to tell it's a mix. Maybe you can.
It doesn't work as well as in gangnam style.
I didn't take time to try to understand why. Either this is because echonest's analyzed mp3 isn't the same as mine. Or the function to compute distance between beats isn't generic enough.
The Echonest stuff, done over the selected works of an artist could make for some interesting mashups of their work.
Someone should analyze why this song is so catchy.
The major I for the third chord is the really key piece of that chord progression. Shifting up and down chords by step is pretty common in pop music, but shifting into major I the first time then the flat 9 dominant the second time (especially with the natural 7 right before it!) is a powerful harmonic one-two punch.
I don't want to be 'that guy', but the other guy responding to you has it totally wrong. Try to plunk out chords on the piano with the music and see for yourself.
So, to clarify, I'm not claiming there is a III in the original key, I'm referring to the III chord of the relative major key.
For classical music the working key is constantly changing and often two theorists would disagree on the "harmonic meaning" of a passage. One telltale sign of a key change is an x-V-I progression (in the new key) where x is any secondary chord that leads naturally into the V. Bonus points if the x or the V don't work in the old key; if you're in C major and you hear a D7, you know something's up.
I also like the helpful visualization below that shows which part of the song it is currently using.

I almost always understand Americans, apart from a few movies where they speak rapidly with background noise.
Here's an example of what it's like: (http://youtu.be/q-cAnFbEXY0) - it's almost recognisable, but not quite.
So, mashing together sounds to create fake words can create something tantalisingly close to what I'm expecting to hear. Mashing a bunch of random words together usually doesn't work, but putting a Markov chain in the again creates something that gives the initial feeling of "this is not nonsense".
And for most songs you probably could sting random words together without so many people noticing; random sentences would probably be fine.
Where are you from? (i.e. What kind of accent do you have?) I find it strange that you'd have to enunciate less to be understood ordering water. If you pronounce "water" with a British accent (http://en.wiktionary.org/wiki/water#English), Americans should generally not have trouble understanding you.
I'm not kidding, "water" is never understood, across a lot of California.
For example from October 20th to October 22nd I listened to Kanye West 200 times in a row and I've listened to "Bob Dylan – All Along The Watchtower" 717 times in total. Music directly reflects my mood so if I'm happy for 6 hours and find a song that I find to be happy then I have no problem with it on for that entire time.
Here's a graph of my listening habits from lastgraph that will show big patches of a specific artist: http://lastgraph3.aeracode.org/static/graphs/graph_228708.pd...
With that in mind, do you really expect the author(s) to tackle the vagaries of cross-browser bugs in bleeding edge web-audio API's?
They'd then stick a little graphic on the page saying "This site works best in [Browser name]"; often with a download link.
When Nux says "Seems like we're going back to "Built for Internet Explorer" days." I guess they're saying "It seems that we're going back to a time when people tweaked their websites to work with a particular browser, rather than concentrating on standards compliant code and cross browser compatibility".
the real difference is Ableton doesn't have the ability to automatically chop the song into logical parts. Maschine can do this, but it doesn't automatically play subsequent parts based on properties on the current one.
Btw, quick bug report: doesn't work for me if open in non-active tab in Chrome 22.0.1229.94 on Mac OS X 10.8.
Good fun and now do an automated version where ppl can paste their youtube links.
I can confirm this bug too.
Random aside: I just noticed that after you drag the Gangnam tab out to its own window, then you can open other tabs in that same window, and it doesn't put the Gangnam tab in the background anymore. But if you put the tab/window back in the original set of Chrome tabs, then it will.
You would have to improve the program a little bit, but this concept being realized with a vast music library?
Sounds quite interesting...
Anyone else experiencing this?
Warning: if you watch it, the lyrics will get stuck in your head. http://www.facebook.com/photo.php?v=10101449851143489
