Changing Playlists afer the Songs Are Edited

[Wrahn]

I put together a Christmas Playlist and after I ran through some songs, I used edit to change some information for the songs. When I re-open the playlists the edit was not on the play list songs. I know I can add the edited song to the playlist and then delete the old song, but is there another way to change the information on the songs on the playlist?

Thanks,
Wes
