This stay-open applet watches your playing tracks and when an un-rated track starts playing displays a window with a demand it be rated.
While you could easily rate the current track from the iTunes icon in the Dock, this script interrupts you and compels you to do so.
You may prefer the more modern Rating Notify.
This window will pop up when a new song begins playing.
