Guests can request songs at your venue via the Moodby app. You don’t need additional hardware to use it.
Once they make a choice, you will see it in the request queue at the bottom right.
If there are no pending requests, the track starts immediately after the current one ends. Those who follow get in line.
No restrictions apply on canceling or blocking any requested song during playback or before it. It is still you who controls the music in your venue.
