Jaudiotagger是jid3lib的扩展，比jlid3lib强大更多，支持更多格式。
MP3信息的读取：
try {
MP3File file = new MP3File("mmt/sdcard2/Music/大艺术家.mp3");
String songName=file.getID3v2Tag().frameMap.get("TIT2").toString();
String singer=file.getID3v2Tag().frameMap.get("TPE1").toString();
String author=file.getID3v2Tag().frameMap.get("TALB").toString();
System.out.println(new String(songName.getBytes("ISO-8859-1"),"GB2312"));
System.out.println(new String(singer.getBytes("ISO-8859-1"),"GB2312"));
System.out.println(new String(author.getBytes("ISO-8859-1"),"GB2312"));
} catch (IOException e) {
e.printStackTrace();
} catch (TagException e) {
e.printStackTrace();
} catch (ReadOnlyFileException e) {
e.printStackTrace();
} catch (InvalidAudioFrameException e) {
e.printStackTrace();
}这样输出的格式为：
Text="大艺术家";
Text="蔡依林";
Text="MUSE";
下面是用Jaudiotagger提取MP3图片，并将图片显示出来的代码：

File sourceFile = new File(url);
MP3File mp3file = new MP3File(sourceFile);
AbstractID3v2Tag tag = mp3file.getID3v2Tag();
AbstractID3v2Frame frame = (AbstractID3v2Frame) tag.getFrame("APIC");
FrameBodyAPIC body = (FrameBodyAPIC) frame.getBody();
byte[] imageData = body.getImageData();
Image img=Toolkit.getDefaultToolkit().createImage(imageData, 0,imageData.length);
System.out.println("img----" + imageData);
ImageIcon icon = new ImageIcon(img);
FileOutputStream fos = new FileOutputStream("D://test1.jpg");
fos.write(imageData);
fos.close();
System.out.println("width:"+icon.getIconWidth());
System.out.println("height:"+icon.getIconHeight());
getImg(icon);
}
public static void getImg(ImageIcon img){
JFrame f = new JFrame();
JLabel l = new JLabel();
l.setIcon(img);
l.setVisible(true);
f.add(l);
f.setSize(500, 500);
f.setVisible(true);
}
