PartySpot is an Android application devloped to enable users to collaborate on their music playlists.

PartySpot synchronizes the playlist's playback across multiple devices so that music throughout the house is playing at the same time, on the same song. Guests can also suggest and upvote/downvote songs, which the host can easily add to the playlist.

The app was built in Java using the Spotify SDK.
