How do you remove all metadata from a mp3 file. For example album art. I want to this because merge couple of files into an existing but use the art.?

There are a few ways to remove metadata from an MP3 file. One way is to use a software program like MP3tag or MusicBrainz Picard. These programs allow you to view and edit the metadata of MP3 files, including album art. Simply open the MP3 file in the program, select the metadata you want to remove, and then click the "Remove" button.

Another way to remove metadata from an MP3 file is to use a command-line tool like exiftool. Exiftool is a powerful tool that can be used to view and edit the metadata of a wide variety of file types, including MP3 files. To remove metadata from an MP3 file using exiftool, simply open a command-line window, navigate to the directory containing the MP3 file, and then type the following command:

```

exiftool -all= "" yourfile.mp3

```

This command will remove all of the metadata from the specified MP3 file.

Once you have removed the metadata from the MP3 file, you can add the new album art by following the instructions in the "Adding Album Art to MP3 Files" section below.
