I use Winamp as my main player. I've been reformatting some tags on files I've had around. They sometimes include info written in the URL, Composer, Encoded,etc., tags that I sometimes need to adjust, eliminate, or apply across all mp3's in a set.
I'd like to know if, and how, I can see those tags in the Mp3tag main window input fields? Can I add extra fields so I can then choose to blank or keep? What happens a lot is I don't know those tags exist until I view the file info in Winamp and then I'm surprised.
