I would like to search the start of the title string for the artist name, in my filenames, the artist name is first, separated from the song name by a "-". so for example johhny bob - here comes the rain
Are we talking about the FILENAME or the embedded metadata field TITLE?
Which data is the source: the FILENAME? Then use the function Convert>Filename-Tag
Mask: %artist% - %title%
If the source is the field TITLE, then use an action of the type "Guess value"
Target: %artist% - %title%
The convert filename tag worked, thank you very much <3
