@Deprecated
public class Scrobbler
extends java.lang.Object
```
Deprecated.
The 1.2.x scrobble protocol has now been deprecated in favour of the 2.0 protocol which is part of the Last.fm web services API.

This class manages communication with the server for scrobbling songs. You can retrieve an instance of this class by calling newScrobbler.
It contains methods to perform the handshake, notify Last.fm about a now playing song and submitting songs to a musical profile, aka scrobbling songs.
See http://www.last.fm/api/submissions for a deeper explanation of the protocol and various guidelines on how to use the scrobbling service, since this class does not cover error handling or caching.
All methods in this class, which are communicating with the server, return an instance of ResponseStatus which contains information if the operation was successful or not.
This class respects the proxy property in the Caller class in all its HTTP calls. If you need the Scrobbler to use a Proxy server, set it with Caller.setProxy(java.net.Proxy).
