Is it playing, in fact, a "completely random CD", or is it playing the same *unrelated* CD? In other words, if you play a particular and specific CD "a", does it always play the same CD "z" after that specific CD "a"? or does it play a different CD each time you play that specific CD "a"?
The reason I ask is that Brennan devices seem to prefer playing albums in the sequence in which they are listed in an internal (text) database, and not in alphabetical order, or grouped by artist, or any other sequence that would make sense tyo some of us. What happens is that initially that internal database is listed in the order in which CDs were loaded into the Brennan device, and then as files are renamed, or deleted, or modified, the order might change to reflect the actual entries on the disc (not the display order, the physical order). That can SEEM random, but if you stop making changes, it is actually a fixed sequence -- just horribly scrambled.
