If you use playlists in iTunes to listen to your music, then you may have noticed that it is impossible to delete a song while viewing the playlist. You might need to delete a lost song or just to remove a song you are too embarrassed to even have on your computer (where did that Wham! song come from anyway?).
I discovered a keyboard shortcut that allows you to do this, simply press control-shift-delete after the selecting the song(s) you want to delete. That’s it, hope it’s helpful for you.
