Here’s a video of an early prototype of a 3D Music Explorer that runs as a Spotify App. The visualization shows a series of interconnected Echo Nest playlists that you can explore. You can fly through your music, listen to anything you see, and create a new playlist starting at any point in the visualization, all from within the Spotify App.[youtube http://youtu.be/q-s7EK6mHR8]
I’m using the awesome three.js for the 3D bits, all the rest is Echo Nest and Spotify APIs. Frame rates with 500 albums showing is 60 FPS Note that there’s a strange interaction between quicktime (that I used for screen capture) and Spotify audio – I wasn’t able to play new songs in Spotify while recording the demo, so there’s no song changes in the video.
