Read id3 v2.4 tags with native Chrome Javascript/FileReader/DataView

You can try using id3 parser on github.

Here’s your updated fiddle that logs the tags object in the console

With the id3.js included, all you need to do in your code is this:

function readFile(){
   id3(this.files[0], function(err, tags) {
       console.log(tags);
   })
}
document.getElementsByTagName('input')[0].addEventListener('change',readFile,false);

And here is the tags object as created by id3:

{
  "title": "Stairway To Heaven",
  "album": "Stairway To Heaven",
  "artist": "Led Zeppelin",
  "year": "1999",
  "v1": {
    "title": "Stairway To Heaven",
    "artist": "Led Zeppelin",
    "album": "Stairway To Heaven",
    "year": "1999",
    "comment": "Classic Rock",
    "track": 13,
    "version": 1.1,
    "genre": "Other"
  },
  "v2": {
    "version": [3, 0],
    "title": "Stairway To Heaven",
    "album": "Stairway To Heaven",
    "comments": "Classic Rock",
    "publisher": "Virgin Records"
  }
}

Hope this helps!
