Roundup of Echo Nest hacks at Stockholm Music Hack Day

Tristan at the Stockholm Hackday

The first music hack day of the new decade is in the can. There were lots of great hacks produced over the weekend.  Here are some of the hacks that used the Echo Nest APIs”

  • – PresentRadio is a QT4 application using the open source libraries, it has metadata views and muchos dataporn provided by Echonest. It looks out for local bluetooth devices and will seamlessly switch to the new station when new people arrive/leave without interrupting the track.
  • All In My Box Allows non-djs to whip up sweet 1 hour mixes in seconds (err, minutes, considering the time to actually beat-match the songs on the server). The drag and drop interface allows users to choose genres and artists and drop them onto a timeline. We use the Echo Nest api to get tracks from the selected genres and artists and stitch them together to create a mix that flows from artist to genre and back again. Echo Nest Prize Winner
  • Echo Nest Midi Player – The Echo Nest Midi Player is a small box you plug into your music instrument (with midi protocol), and on the internet. In real time it plays tracks analysed on the Echo Nest. Echo Nest Prize Winner
  • discoveOMaticdiscoverOmatic allows you to discover new artists and tracks while listening to the radio or even your own collection. Simply select the radio station you’re currently listening to (currently on BBC brands supported) and we’ll do the rest. If you’re listening to music through other means and scrobbling to we can provide recommendation based on your currently playing or most recently scrobbled track as well. Discover the great music while listening to what you like with the discoverOmatic!

  • All Music Is Equal Take any piece of music and turn it into a “music pupil plays church organ, using a slightly stumbling metronome” version!


  • Mystery Music Search Mystery Music Search gives you the results for whatever the person before you searched for. Heavily inspired by, and using the new Echonest search_tracks api. Echo Nest Prize Winner

  • MashboardMashboard is a simple dashboard for your SoundCloud tracks. You can analyze the tracks using the EchoNest analysis API, returning Key/Mode, BPM, and song section information that is written to the appropriate metadata fields in the SoundCloud track. What’s more, you can scrobble your tracks to your profile while listening on your Mashboard profile page. Last, but certainly not least, you can trade your SoundCloud tracks on TuneRights by making and accepting offers from other users, managing the shareholders of your tracks, and bidding on other tracks in the TuneRights system.

    Is anyone else having trouble with All Music Is Equal? I never get any sound, even when the big red PLAY turns to STOP.
