Oh, that's good: the tag fields are filled.
THis means that you can use that data to create a new filename (I would not swap it - the information in FILENAME is much shorter than in TITLE).
So try for a single file first:
Format string: %title%
I do not see the contents of the field TRACK but I see a number in the filename. If TRACK is already filled - fine. If not, then retrieve that information first:
Pattern: %track% %dummy%
(There is a preview for reassurance)
To get the whole information of TITLE and TRACK into the filename, use Converter>Tag-Filename
$num(%track%,2) - %title%
(There is a preview to show you the new filename)
All this works for all the selected files in 1 go.
