I have noticed same problem as well. The USB library is not A-Z in order? I have organised A - Z Folders on USB stick, in which I have the corresponding artists (for quick access). The A - Z Folders are displayed in the correct order, but the Artist Name within each folder start off ok, but it seems like they are organised by date also, but the date takes priority?? This never happened with the sdj1 I used to have?? Can anyone help? ADJ - Maybe a software issue?.
