That free U2 album

I have not used iTunes on my Mac Mini til now, it's way different from the old style one I have on my G4!!! Anyway, I seem to have accessed the new U2 album Songs of Innocence as I can see them in iTunes but they can't be dragged and dropped into my Library because my computer is not "authorized." I keep getting that msg. What does this mean and what do I have to do to authorize it so I can have this album in my Library? It's probably so simple :)



Thanks
