The only time I rename songs is when I'm researching album names for the songs/artists on WMP 10. Then, if WMP 10 comes across the songs/artists (as well as the albums) THEN I update the titles, but only in WMP 10. I don't mess with the original names in LW itself (unless I absolutely have to). So if I have (song title here) by (group name here) in my LW library, it will be listed EXACTLY as I downloaded it from LW.
