Do you mean something like this:

playListDS rec = new playListDS();
if(File.Exists(Server.MapPath("~/playlist.xml")))
{
    rec.ReadXml(Server.MapPath("~/playlist.xml"));
}

int id = int.Parse(rec.track.Rows[rec.track.Rows.Count - 1][0].ToString()) + 1;

if (ViewState["Filename"] != null && ViewState["Cover"] != null)
{
    playListDS.trackListRow row = rec.track.AddtrackRow(id.ToString(), "mp3/" +
                              ViewState["Filename"].ToString(), txtartist.Text,
                              txtalbum.Text, txttitle.Text,
                              txtannotation.Text, txtduration.Text, "mp3/cover" +
                              ViewState["Cover"].ToString(),
                              txtinfo.Text, txtlink.Text);
}

All you need is the new added row? If so, you get the new row from the AddtrackRow method.
