Half Ratings in iTunes

1. Copy this:
   

   defaults write com.apple.iTunes allow-half-stars -bool TRUE

2. Open Terminal (I love little hacks via Terminal)
3. Paste (Command-V) into Terminal and hit Enter
4. Close and Re-Open iTunes

(via TUAW)

If you use SizzlingKeys, it now displays half-ratings, and hopefully will add the half-rating function soon.
