fixed the issue. Will look into that further The value 20646520 is in ASCII @A.
ObjectInput/OutputStreams use a "magic" value at the beginning of the stream, to indicate it complies to the special serialization of the objects. (I think this was 0xCAFEBABE, but I'm not sure)

I hope this helps . You've likely got your streams in a twist.
When you construct an ObjectInputStream, the constructor reads the first two bytes from the stream expecting them to be the "magic values" that should be present in an object stream. If they're not there, it throws the StreamCorruptedException (this is all in the ObjectInputStream source code).

it fixes the issue I have another problem. , You have made it far more complicated than you need to.
code :
Socket socket = new Socket("", 3000);
try {
  ObjectOutputStream oo = new ObjectOutputStream(socket.getOutputStream());   
} finally {
ServerSocket clientConnect = new ServerSocket(port);
System.out.println("SimpleServer running on port" + port);

Socket clientSock = clientConnect.accept();
try {
  ObjectInputStream stream = new ObjectInputStream(clientSock.getInputStream());
  String[][] songs = (String[][]) stream.readObject();
} finally {

this one helps. Don't create a new ObjectInputStream every time you read an object (or a new ObjectOutputStream every time you write one). Use the same streams for the life of the socket.

seems to work fine ObjectInputStream expects a header in the stream that is written by ObjectOutputStream. So If you use one, you need to use both.
As your sample doesn't really need ObjectOutputStream, you may just want to not use ObjectInputStream.
