I'm looking for the best app to store your CD and DVD collection on iPhone?

What is the best app to store your CD and DVD collection on iPhone? I've just been looking at a app called My Library what costs £2.49 but I want other peoples opinions who use this sort of app.

With DVD Shelf, your collection is always at your fingertips so you can look items up anywhere and anytime, whether you already own a CD / DVD or have stored it in your wish list.
