Guy Oseary is in a predicament. Madonna and U2 are collaborating on a new album, and they are debating on the album art. Madonna likes 4 of them based on a particular property and U2 likes the other 4.

 

Guy was planning to release two albums, highlighting the preferences of the different musicians, but he can't remember which ones they preferred, nor what that property was that distinguished them.

 

Use your reasoning to see if you can sort the cards into the two piles (one for Madonna and one for U2).

 

If you get it right, you'll be given a code (make sure to write it down!).
