Editing MP3 tags

I would like to have a script to open a folder of MP3 files or select those files directly, and make the title tag the same as the file name.
Doug’s script doesn’t seem to work in Music, but I would find it more convenient to convert files outside of Music. I would not find editing the filename to remove .MP3 a big problem, but I can’t figure out how to get each file, its name, and to address the title ID tag and change it.

You added the mp3 tag neatly and that’s good. But you didn’t provide your script, which is not welcome here. Therefore, you are not answered. You just need to login and click on the required tag, and you will find a lot of what you need.
