Answer 1

One more library available at https://github.com/aadsm/JavaScript-ID3-Reader

In its simplest form:

ID3.loadTags("filename.mp3", function() {
    var tags = ID3.getAllTags(filename);
    alert(tags.artist + " - " + tags.title + ", " + tags.album);
});

by specifying specific tags:

ID3.loadTags("filename.mp3", function() {
    var tags = ID3.getAllTags(filename);
    alert(tags.COMM.data + " - " + tags.TCON.data + ", " + tags.WXXX.data);
},
{tags: ["COMM", "TCON", "WXXX"]});

or even by specifying shortcuts instead of cryptic tags:

ID3.loadTags("filename.mp3", function() {
    var tags = ID3.getAllTags(filename);
    alert(tags.comment + " - " + tags.track + ", " + tags.lyrics);
},
{tags: ["comment", "track", "lyrics"]});
