Itunes is pissing me off please help!?

okay so heres the deal. my desktop is flooded with things and i was cleaning it up. So i made a folder and put all my songs form my desktop to the folder. Now its clean. But now all my songs have to be relocated in itunes for me to listen to them. its making me find each and every song... i have like 100 songs. is there a way to automaticly relocate them?
