I made this system myself. It is a radio system that plays through a playlist of audios (shuffled).

Once a song is played, it’s taken out of circulation until there are no songs left in the playlist, from which every song is put back into the active playlist to resume the cycle. This prevents the same song from playing twice.

It works off of both a GUI button to turn on the radio and physical ingame radios. The cool part is that it will consistently play the same songs across all radios and GUI radios. If you turn off your gui radio and turn on a physical one, it will keep playing where it should in synchronization.
