Find duplicate/identical files by title

Hi, I hope this has not been asked before, but apologies if it has. Can anyone advise a script or a search to reveal identical/duplicate files (same title by same artist but different file name).
I plan to place two folders of 5000+ MP3s each into one master folder, open it in MP3Tag, and then discover how many identical files are in there and conversely how many orphan files there are to each folder.
I hope this is possible and thank anybody who can help me.

You can use the export tool (Ctrl+E) to find files with the same tag values.
Make a new config with this content:

$filename(Dupes-Artist Title.m3u8,utf-8)
$loop($lower(%artist% %title%))$loop($lower(%artist% %title%))$loopend()$ifgreater(%_max_counter%,1,'#Same Artist Title: '$if2(%artist% -- %title%,-- empty --)
$loop($lower(%artist% %title%))%_path%
$loopend(),)$loopend()
