Recently downloaded song from ITunes needs to be constantly reauthorized.

I preordered an album, it automatically downloaded on the day of release. Of the 10 songs, 6 play but 4 won't. Each time I try, it says the song is not authorized. I type in my name/password, it says I am authorized on the computer, but song won't play.

I try process on my IPhone, I do name/password, it just simply goes away, nothing happens.

Previous community threads say that if you repurchase/redownload the songs it will work. Those options don't show in my iTunes on either PC or IPhone.

Any other options?

Thanks much!!
