AvRack? Wazzat? If it came with your burner then isn't it burning software?
Anyway, for playing the songs (you have PC right?) when LW is open, click Tools->Options->saving and remember the path that is indicated there: it tells you where the completed dlds go. Now open a new window in your browser and go to that folder (it's called Shared). Do what you want with the files in there.
