使い方の例
1,基本的な使い方

//In its simplest form:
ID3.loadTags("filename.mp3", function() {
    var tags = ID3.getAllTags(filename);
    alert(tags.artist + " - " + tags.title + ", " + tags.album);
});

2,特殊用法

//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"]});
