Playlist problem
 

I have not been able to find a way to remove songs from playlists one by one.?
This is absolutely necessary, since sometimes when one makes a good playlist of, say, 200 songs, and then grows tired of some particular songs, it is too much to do the whole list again w/o those songs.
Would it not be a basic attribute of ANY media player to allow removal of single songs, as well as multiple (tho not all).
At the moment the only option for removal is to remove ALL songs on the playlist.
