I've recently got a new Windows laptop and downloaded and installed the latest iTunes (11.0.2). All my music (over 5000 songs) went into iTunes fine, just as they were on my old laptop. However I have now noticed that when I download new music and add it to my iTunes it won't allow me to edit the songs through "Get Info" even though the songs I transferred from my old laptop can be edited perfectly fine. Can anyone help? Thank you.
