I created a 'filename->tag' conversion rule to split the filename and extract just one word from it. The new tag was named 'YEAR_NAME' and really did the trick I needed.
When I opened one file with the new tag, I noticed that the TRACK tag was changed from '01/07' to the song's title. This has occurred to all files that contain the new YEAR_NAME extended tag.
To reproduce:
-
create a file with year info in its filename like this "10cc - I'm not in love [1975].mp3"
-
the conversion rule extracts the "1975" token and stores in extended tag YEAR_NAME
%artist% - %track% [%year_name%] -
check the TRACK tag
This is the file that has the new extended tag:
Files that don't contain the new extended tags show the original untouched TRACK info.
