how to delete a file from the list on Windows media player 11?

[Zong]

when I right click on a file, it only shows "remove from list."
The thing is I have so many music file on my computer. I have to look through the library, most of the time I can't find it. If it can be deleted from the playlist, it will be more easier. Or there is another way?

if you want to delete something, you have to delete it from the library, not the now playing list
