I am using MP3Fm v2 to transfer songs to my NWE-507 and am finding that unless the track number is actually in the file name, that the songs will be in random order on the Walkman. I believe that I have tagged them correctly , but no matter what I do, unless the track number is in the file name, the songs will not be in order. Can anyone confirm if this is the case, or am I just doing something wrong?
