Entity Framework 4.1 and "Live data"

[Kennet]

Picture the scenario like this: A playlist with songs that GridWiew shows and when I outside the application update the "playlist" I need GridView to smoothly show the updated data.  Data contains "songname", "playdate", "sortOrder"

Showing and edit the playlist is easy, but how do I do the "live" update best?  It could contains many rows like 20000;

var query = from o in contex.playlists
                        where o.date >= _today
                        orderby o.playdate, o.sortOrder
                        select o;

            _playlists = new ObservableCollection<playlist>(query.ToList());

            radGridView1.ItemsSource = _playlists;

Any ideas?
