Crowdjuke is a new app, created by Facebook partner engineer Matt Kelly. The as-yet-unreleased app pulls the music preferences of friends that have RSVP’d to a particular event, then uses Rdio’s music library to create a playlist combining their tastes.
Nothing we haven’t seen before, the real problem with crowd-sourced playlisting is how to create a mix that flows and sounds good. Apps like this work fine if you’re only inviting a few people who all have killer taste, but any party that’s a little more diverse will almost always include a few people with ‘different’ tastes. While Crowdjuke doesn’t solve this issue entirely, it takes a good first step, using The Echo Nest’s API to eliminate songs that aren’t deemed “danceable” enough for a party atmosphere.
