Perhaps if contacting IA you could ask if we could have a rational, repeatable, and controllable way to play MP3 tracks on USB in a manageable order, perhaps alphnumerically by title, or even something as wild as in the order of the track numbers? It really isn't possible to do this at present, and the unpredictable randomness is tiresome. On a vehicle as expensive as the Grenadier, it really is poor that the only way to play an album with tracks in the right (or even a predictable) order is to do it from a smartphone.
