Auto Renaming of filenames if duplicated

I'd rather create a playlist with all duplicate tracks.
Use File > Export (Ctrl+E) and create a new config with this text.

$filename(Dupes-ArtistTitle.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()
