title: Python - Add ID3 tags to mp3 file that has NO tags
body: <p>I get a lot of podcasts that have no ID3 tags in them. I've tried a number of tools that I could use to loop through directories and add title and artist info to the ID3 tags, but they fail. I've tried ID3, eyed3 and mutagen. Most of the time if a file has no ID3 tag these modules fail.</p>
  
  <p>Can someone recommend a good ID3 tag editor library that will work through loops? What else do I need to know about editing/adding ID3 tags when they're 100% blank? It's getting frustrating trying library after library only to find that the problem remains.</p>
  
  <p>Thank you.</p>
