Hi John,
Take a look at the similar question on C#:
http://social.msdn.microsoft.com/Forums/en-US/fffe6b6c-e412-42ba-a001-d29ee5f3c912/read-the-metadata-of-songsmp3-from-the-internet?forum=winappswithcsharp, you have to get all the music download and read the data from it, because most of the information
that you are seeking is near the end of the file.
I wrote some code two weeks ago for fetching the ID3 of the mp3 online in C# and it should be more or less same with JavaScript:
HttpClient httpclick = new HttpClient();
Uri uri = new Uri(yourMusicAddress, UriKind.Absolute);
var httpResponse = await httpclick.GetAsync(uri);
byte[] b = await httpResponse.Content.ReadAsByteArrayAsync();
//read ID3, first 3 is 'TAG'
string title = System.Text.UTF8Encoding.UTF8.GetString(b, b.Length - 128+3, 30);
string MusicAuthor = System.Text.UTF8Encoding.UTF8.GetString(b, b.Length - 128+3 + 30,30);
string MusicRador = System.Text.UTF8Encoding.UTF8.GetString(b, b.Length - 128+3 + 30 + 30, 30);
Hope it can help you.
Best Regards,
--James
