unprotecting itunes files

i hate buying tunes off itunes and then not being able to play them on anyone's computers. it's my tune and should be able to play it anywhere right? well that's how i feel. to me it's like if i bought a cd and i could only play it on my cd player. if i make up an mp3 cd i want to play those tunes anywhere.

here's an open source program that will unprotect all your itune files.
