I sympathize with the issue stated here. For those of us who play live with mp3 files (created with BIAB), playing the correct order is a big deal. Another is having the mp3 device stop at the end of each song, then, letting the player decide the next selection. My Walkmans won’t do that. They immediately play the next song in the folder. Often one needs to pause to chat with the audience, search for requests, tune the guitar, or whatever.
