Some of my CD's will import to itunes but will not go to other devices. Some will, some won't. All CD's are on my itunes on my main computer
Did you import all the CDs via iTunes import feature?
Do they all play in iTunes on the computer?
Is there anything different about those that do sync to the iPod and those that do not?
Try deleting the ones that do not synced from iTunes and reimport and try to sync.
