title: Changing a MP3 files ID3 tags
body: <p>I found a website recently that allows you to upload a file and change its ID3 tags (<strong>Image</strong>, <strong>Title</strong>, <em>all that other stuff</em>) and currently I am storing files in a directory after I parse them from another website before pushing them externally.</p>
  
  <p>I am wondering if someone knows a library where I can read how to change the default ID3 tags in <strong>PHP</strong>? Is this a already existing feature with <strong>PHP</strong>?</p>
