Wincent Colaiuta has released version 2.5 of his iTunes utility Synergy. Itis a maintenance update "intended largely to fix an issue when using half-star ratings in iTunes 6.0.2 or later," he said. Itis also qualified for use with iTunes 6.0.3. Synergy (US$10) puts play/pause, next track, and previous track buttons in the menu bar, along with an optional floating window that displays track information and album art, which it retrieves from Amazon.
