Crowdjuke Taps Facebook To Create Perfect Party Playlists

Every Music Hack day has a couple of themes, and crowd-sourced playlist creation was especially big both in San Francisco and New York.

Crowdjuke, which won Music Hack Day SF sponsor MTV’s prize (a nomination for an MTV O Award) was the best of the lot. 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.

Attendees who forgot to RSVP (or just show up out of the blue) can text their preferences to a number via Twilio to have their songs added to the party playlist in near-real-time, as well.

This is all well and good, but nothing we haven’t seen before, concept-wise. 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 radically different tastes (or a few pranksers who’ll throw in the “The Chicken Dance” just to rain on the parade).

While Crowdjuke doesn’t solve this issue entirely, it takes a good first step, using ( publisher) The Echo Nest’s API to eliminate songs that aren’t deemed “danceable” enough for a party atmosphere.

So far, a number of people have tweeted that they plan to use Crowdjuke to soundtrack upcoming events.

Hopefully, they’ll invite people with good taste.
