AJ & McCall Drop the Mic on Ed Sheeran’s Collaborations Project #6. There are 15 songs and two have been released so we know who Ed is working with, but there’s 13 songs and 19 blanks left. It’s a fun guessing game because you can almost make out some of the letters that are blacked out so AJ, McCall and Producer Butterz are going to try and guess who the other artists are and see who does best. Any guesses for who should be in the blanks?  (left  to  right  is AJ,  McCall,  Producer  Butterz)
