Talked to Mercedes about this
Mercedes called me after I asked a question about the music playback on their site.
They said that the random function is what it is, there's nothing that can be done to change how it works. They did say that the stereo doesn't keep a memory of what tracks have been played after you shut the system off. When you start back up, the randomizer works on the collection of tracks as if for the first time. So this can contribute to some repeats in the track playback order. They also said not to organize music in a folder tree deeper than 8 levels, because the system doesn't access anything beyond that.
