If you want to delete the existing content in
Album ("Hits")
Track ("2")
you can select all the songs from the same Album ("Hits") and then click on the tag
Album
and select the entry to blank/delete the content in this tag for all selected songs.
Repeat this step for the tag
Track
Don't forget to Save your changes by pressing CTRL + S or click on the blue floppy disc symbol in the toolbar.
The Artist is already filled with "Michael Franks".
Now you add the Title "Eggplant" in this case.
And PLEASE
The format string is
Percent dummy Percent Dot Space Percent title Percent %dummy%. %title%
Every character is important, including the dot and the space
I would say "bingo".
And now: if you let MP3tag import that data into the tag field TITLE, (as you have done already as the screenshot shows) you will now see the ARTIST and the TITLE in the tag panel.
BZW: in none of the examples did "02. eggpant.wav" appear either in ARTIST or in TITLE.
So where do you want to see "ARTIST TITLE.wav"?
