ffmpeg random mp3 audio play

I stream images from an IP camera to an external player and play back mp3 files as background music in a loop. In order to keep the playback continuity, I combined several mp3 songs together. Each time the external player is started, the background music starts from the same track (which was saved first as a result of joining mp3 files). When I start the player, I would like to run a random mp3 file as background music and play the whole list in random order and additionally in a loop. Here is my current camera streaming code + logo position + mp3 playback
