Leave the thing off the back and I like it... the concept is the same as the other one, but the execution is different, and I like that yours is simple. I'd buy this if there was nothing on the back for sure.
Um, there's been a zillion different kinds of jokes and takes about cd pirates before fatheed's sterling example of the concept, so no, these aren't the same at all. I do enjoy your dress-up theme here, but it doesn't need the back design to understand what you are getting at. An eyepatch on a cd is just quite funny to look at.
