Build complex Spotify playlists by wiring together components in a visual editor. Mix, filter, and sort tracks from any source (with Last.fm and Musicbrainz support). Combine multiple playlists, saved tracks, and recommendations. Filter by genre, audio features, popularity, and more. Schedule programs to keep playlists updated automatically.

This app has a pulldown list of all of The Echo Nest genres - http://static.echonest.com/demo/GenreSampler/GenreSampler.ht...

Built this weekend at Music Hack Day Chicago

I updated the app, to keep the help info there. It is a good suggestion. Thanks!

not stupid at all, I came to the comments to find out what 'review times'meant is well. I had the same confusion.

gave up after having to click through 4 ads to see something bigger than a postage stamp

yep, that did it, thanks much yuchi!

magenta - I spent about 10 minutes trying to center it all, but I couldn't get Raphael.js to behave, so since it was a weekend hack, I moved on. But yes, it would look much nicer if it was centered, even more so if a designer did the design ...

hornbaker - for a live DJ performance check out this similar app - http://static.echonest.com/BeatDriver/

Infinite Gangnam Style was built this weekend at Music Hack Day Reykjavik in Iceland. Check out the full list of hacks here:

Dave - I like hackathons. In particular I like the 24 hour constraint. Having to build something in 24 hours (really probably 18 hours), forces me to make decisions, to get to the heart of the problem. Similarly, building something that I know I will only have 2 minutes to demo makes me really focus on what is important. I think the constraints lead to more creativity, just like the Haiku with 17 verses and 3 lines opens the door for whole libraries of verse.

Some more of my thoughts on hackathons here:

There's no central database of ISRCs, so even if you have an ISRC in your hand there's no way to find out what artist and song title that ISRC represents.

There may be some info returned, but I didn't dig into in too much. Once I figured I could run through the whole set in less than an hour for less than 10 bucks, I had all the info I needed.

yes, the number and size of EC2 instances can be set by switches on the command line when you launch the job.

Hi Chapel - you suggest I could have been more objective, perhaps using other people's music collections and getting their own personal opinions. That, of course, would still be a subjective evaluation. It would be better, of course, more opinions means more data. In fact, I welcome people to make the same evaluation with their own collections. Enroll them in all 3 systems, create some playlists and evaluate them. Since most people don't have access to Google Music yet, this is hard to do. Still, you can look at the playlists that I generated and make your own WTF opinions about them. Or better yet, count the WTFs in the playlist Google created during the Google I/O keynote. You can see it at 28:29 of this - http://www.youtube.com/watch?v=OxzucwjFEEs Here's a screencap. https://skitch.com/plamere/r9x2k/youtube-google-i-o-2011-key...

There's no objective evaluation of playlists. I've proposed a simple, subjective one that I think gets the job done. I'm happy to try other ones if you have something to suggest.

Hi ABrant - yes, indeed we are looking at extending our docs and tutorials in all sorts of ways. Thanks for asking. -- Paul (Paul@Echonest.com)
