How to make a gathered song/mp3 into individual song/mp3's?

I’ve downloaded a music file from The Glitch Mob, when I opened the file it was their new album in one mp3. Thus when I play it on iTunes it would be 1hr long. How can I make them into their individual form? Such as when you just download one song or when you download an album and you unzip the file and you’d get all their songs of that album in one folder.
