I’ve already rated most all my songs in iTunes, but I’ll always acquire more to rate. So, thanks to Alex for posting this tip for rating songs without the smartlist dynamically updating and stopping playback. I had the problem at home, but just went with it. “The solution? Set your ‘Unrated’ [Smart] playlist as the source for Party Shuffle then the songs stay in the queue and keep playing – it’s that easy (and unintuitive).” You’ll need to enable Party Shuffle for this. Edit > Preferences > General. Check “Party Shuffle”. Jon Poyner, you reading this?
