Thanks... the songs are in my iTunes folder on my PC where all my other music is (in the my music/iTunes/Beatles (for example) folder. Also, some of my playlists aren't there. The size of my iTunes on my iPad is much smaller than in my iTunes folder but in iTunes they're all checked, I've tried the sync with and without "sync only checked items" (under summary when my ipad is connected). Although my iTunes folder is much bigger than the storage space on my iPad, I had unchecked things... Thanks a lot, I really appreciate the help.
