I have a feeling this is in options somewhere but I can't see it. Anyway, I updated an MP3 to have no Composer. When I upload it to my server the composer field still exists. I have just noticed that if I right mouse click in Windows and edit ID-Tag the composer field is still displayed as the old composer.
How do I make MP3TAG update everything and how can I get it to display whatever is being used by DBPowerAmp to displayed the composer field with the old value in it?
To remove just the APE tags set
APE: read, delete on, write: off
all ID3: off
Load the APE files,
Select the APE files
Right-Click on the selected files and select "Remove tag"
The tag data in the file list should now be empty.
Go back to Tools>Options>Tags>Mpeg
and set ID3: Read, write, delete on as you need it (I would set ID3V2 to read, write UTF16 and delete)
and set APE on only for Delete.
Return to the files list and press F5 to refresh the list - you should now see the ID3Vx tag data (again).
