How do I unprotect my songs on I Tunes?

They say there protected ACC and I can't convert them to mp-3 status! Please someone help me=[ and i cant burn any Cds cause we dont have any. (The reason why I want to unprotect my songs is cause I want to download songs for my one true media cideo for youtube)|||burn them on a cd, and then RIP the songs using musicmath or windows media player and make sure the format is mp3.|||You need to buy a converter. I use NoteBurner for the same reason. Works like a charm.
