    Music Fetcher service interface defined in service registration xml.
    Service client needs to create a request using interface name
    "com.nokia.services.media.Music" and set string to show in
    opened views title as a request argument.

    Example usage:
    \code
    XQApplicationManager appMgr;
    XQAiwRequest* req = appMgr.create("com.nokia.services.media.IMusicFetch",
        "fetch(QString)", true);

        connect(req, SIGNAL(requestError(int,const QString&)),
            SLOT(handleRequestError(int,const QString&)));

        // Set argument for request (title for opened views)
        QList<QVariant> args;
        args << QVariant(QString("<title to show>"));
        req->setArguments(args);

        // Make the request
        if (!req->send())
