Too vague. Just these songs, or all your purchased music? Any messages from iTunes? The computer is authorized to play them?

they used to work great. but all of a sudden dont work. I never saw any error mesage. Computer is authorized, they just stop working. First 1 didnt work, then it spread out to 3.

Did you move your Users folder? I had a problem after I did that, adn it turned out that there is something in the Shared folder that iTunes needs. Probably not your scenario, but it might help somebody.
