The app is perfect for parties, road trips, or group events, and users can choose from the full catalogs of both Spotify and Youtube.

With musiQ, playlists can be password protected, and hosts can add a special admin password to grant certain members extra privileges, which is very useful in large groups. Users can view the playlists nearest to them and also search for playlists anywhere in the world to join.
