Soundemocracy is a 'democratized' web-based Spotify-driven playlist that grants everyone in a given venue the ability to contribute music to the playlist. This can be done via the mobile application with which the user can submit a song, and vote to bump certain songs up or down.
This project was created during a 6 hour hackathon in Stockholm. The app is a responsive web-app that runs on a MySQL and PHP driven backend and queries the Spotify API by using jQuery and AJAX.
The project is still in beta.
