Like menu item should be greyed-out if song is already Liked (and same for Dislike)

[squintgit]

I use Keyboard Maestro to select the "Playback > Like" and "Playback > Dislike" menu items from any macOS app I may be using when I want to Like or Dislike the currently-playing song.

Problem is, sometimes songs are already Liked or already Disliked. When a song is already Liked and I execute the Like command, it removes the Like. When a song is already Disliked and I execute the Dislike command, it removes the Dislike.

If the song is already Liked, it might be better if the Like command is greyed-out and unable to be executed.

If the song is already Disliked, it might be better if the Dislike command is greyed-out and unable to be executed.
