Well, why not use a Winamp plugin for such things? Because they don't seem to be related to MSN or Plus!
Also you could already use things like "
/run http://www.google.nl/search?q=(!np)". However you'll need to strip the "
Now Playing:" part then, that could be done with a PHP script, also /run refuses to work when the winamp title contains some illegal characters.
If you search the plugins forum you may also find some plugins that have something simular to (!NP) but don't have the "Now Playing:" part in it.
