Remove all unnecessary tags

I would like to remove all but the basic tags from my MP3 files.

Some of them have Covert Art in them, Some have song lyrics

Is there a way I can remove all but the Basic information (Title, Artist, Album Artist, etc)

Trying to make my MP3 files smaller (without changing quality) so I can get a few more on my Phone card.

Thanks

There is an action for that:

remove fields except
Supply a list of fields that you want to keep. Enter their name without % and without any blanks. Separate them with a ;

I doubt that you will really save a lot of space as fields usually take up only a couple of bytes. And by considering the unavoidable padding, you will not see a lot of saving.
And any data that you delete is hard to restore.
