Hi gwindey, and thanks for your post.
Unfortunately the WTV020SD doesn't have a loop function built into the chip so there isn't an easy way to loop a track. The least expensive sound board that will do looping is the Qwiic MP3 Trigger. To loop with this, just ground the trigger pin for the track you want to play and leave that pin grounded all the time. The Qwiic MP3 Trigger will play that file over and over until you remove the ground or power the module off.
