I have 233 songs in my library on I tunes. Yet I am only able to synch 133 of them into my ipod. I have one of those older 4gb models and haven't updated in a long time so I tried today and am frustrated that I can see 100 songs in my "library" that I can get into my ipod. Any suggestions on what I may be doing wrong? If reinstalled i tunes and nothing changed.

Thanks
