I just got a 2 gig iPod Nano from my wife, so I'm selling my 512mb iPod Shuffle. However there is one feature I miss from the shuffle, and thats auto fill. To tell you the truth, other than when I listen to podcasts, I always set my nano on shuffle... but it shuffles the same 500 songs. So I created 2 smart playlists... one that has my newest downloaded music on it, and one that just picks 1.5 gigs of music randomly from my library. But I can't get the smart playlist that grabs the random music to refresh/reshuffle. Is there a way to do this? Why the hell can't Apple give me my Autofill button back?
