    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.Music",

        "fetch(QString)", true);

    if (req)

    {

        connect(req, SIGNAL(requestOk(const QVariant&)),

            SLOT(handleRequestOk(const QVariant&)));

        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())

        {

            qDebug() <<  "Failed to send REQ";

        }

        delete req;
