I've no doubt this is hidden in the deep bowels of 'search' but a little help, piss taking and sarcasm is gratefully accepted on the chin 
I've taken the great step and moved from a PC to iMac, should have done it years ago.
I've moved my iTunes across to the new Mac, but where I had 7,219 items on the PC I now only have 4,421 on my iTunes on the Mac. Those that are awol are both purchased and loaded from CD so there's no connection there methinks. How do I find those that are missing ... still showing on the PC, and move 'em across?
While I'm at it, the playlists didn't move across, so do I have to start all over again?
Thanks for any help, constructive or not, but please keep it simple for a total numpty
