Updating live tiles from Background audio agent?

Question

Updating live tiles from Background audio agent?

I know that you can update Liva Tils with ShellTile of PeriodicTask. is it possible to update the live tiles of background audio agent?

I want to do, for example, when the track changed to the title track on the live tile. Is this possible?

Just did not want to do would have been a few applications of background agents: agent audio and even periodic background agent. Would not this heavy load and impact on battery life?

Update: BackgroundAudioPlayer tried in this way:

ShellTile apptile = ShellTile.ActiveTiles.First();
            StandardTileData appTileData = new StandardTileData();
            appTileData.Title = "Title App";
            appTileData.Count = 5;
            appTileData.BackgroundImage = new Uri("/front.png", UriKind.RelativeOrAbsolute);
            apptile.Update(appTileData);

And I get an error message First() is not found
