title: Detect duplicate MP3 files with different bitrates and/or different ID3 tags?
body: <p>How could I detect (preferably with Python) duplicate MP3 files that can be encoded with different bitrates (but they are the same song) and ID3 tags that can be incorrect?</p>
  
  <p>I know I can do an <a href="http://en.wikipedia.org/wiki/MD5" rel="noreferrer">MD5</a> checksum of the files content but that won't work for different bitrates. And I don't know if ID3 tags have influence in generating the MD5 checksum. Should I re-encode MP3 files that have a different bitrate and then I can do the checksum? What do you recommend?</p>
