Error Code 200
While the SAM Wikipedia indicates:
"200 - requests - Touch OK
Like it said, everything is good don't get greedy!"
The error also indicates that someone else may be streaming on the server and thus not allowing you to connect.
If you were disconnected from the server and for some reason got disconnected abruptly and an error 200 appears upon reconnect, chances are your disconnection from the server did not register properly, so you might be ghost connected. Give it about a minute and the current connection will time out when SHOUTcast realizes that you are no longer connected to it.
