Single Realtime Collaborative Playlist

What is CrowdSound?


Log in with Spotify Premium to build your own playlist, and share it with friends.


Add songs to playlists, including your own, and collaboratively vote to influence what plays next.


Enjoy listening to a playlist of the most highly voted songs, in real-time.



Log in with your Spotify Premium account to create playlists and play songs, or get involved without an account by influencing what plays next with your votes.


Use your device location to find nearby playlists to join, or share your playlist with friends in the area. Passwords allow you to create a private session if desired.

Real-time Input

Begin adding songs to your playlist immediately after creating it, and upvote or downvote songs as they are added. The app will continuously choose the song with the highest number of votes to remove from the queue and play.

Distributed Framework

Any member of a playlist can search for songs on the Spotify server to add, while the owner of the playlist can utilize their Spotify account to play the most requested songs. All information regarding the playlists, the songs on them, and their vote history is maintained, in case you ever want to return to a session.
