For what it worth... I record my listens in a LibreOffice Calc file (similar to Excel) including date, song, songwriter... When I get time to listen to a song, I will do a quick search to see if I have already listened to it... I also always record the next song so when I quit I have a new starting point... the next song up is "The Traveller" by BlueAttitude... it was on page 7 but who knows where I will find it
