Question

Just brought the MacPro and first time using iTune and Yes I authorized the computer. But for a few purchased songs, only 30 seconds of the song plays and for one song off an album, a pop comes up saying I need to authorized the computer, but I do this and it says it is authorized already. I click on the song to play it and this process repeat (saying it is not authorized, then saying it is already authorized)

Answer 1

If your country's iTunes Store allows you to redownload purchased tracks, I'd delete your current copies of the dodgy tracks and try redownloading fresh copies. For instructions, see the following document:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
Otherwise, I'd report the problem to the iTunes Store.
Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
Find the items that are not playing properly. If you can't see "Report a Problem" next to the items, click the "Report a problem" button. Now click the "Report a Problem" links next to the items.
