iTunes smart playlist not syncing to iPhone My smart playlists created in iTunes are not syncing to my iPhone.  I have resolved to copying the songs that are in the smart playlist to a regular playlist to get the playlist onto the iPhone.  Why is it that smart playlists won't sync?
I had the same problem, try:


right click the playlist 
click 'duplicate'
delete the old playlist 
then re-sync your iPhone/iPod or whatever


This worked out fine for me, i then just renamed the playlist taking '1' off the end (you'll know what i mean) - hope this helps!
