I want to write a script that manipulates ID3 tags of mp3 files. I need a tool that reads the tags and outputs it in a format in a machine-readable format. For example, if I want it to output only the title, then it outputs the title, nothing else. I tried different tools like id3 or eyeD3, but they can only be used to write tags or to output them in a human-readable format. Of course I could just filter that output through sed, but it seems unnecessarily complicated to me.
