The seed entry for this grid was 36-across. I don't remember where I first saw it, but when I did, my immediate thought was that it belongs in a crossword. I created this puzzle just around the same time as Kanye West's highly secretive "The Life of Pablo" dropped. That album contains a song called "Freestyle 4", which prompted one of my friends to ask me, "What did you know, and when did you know it?" to which another replied, "insane artist minds think alike". While this was a total coincidence, I'm happy to fan the flames of any comparisons between me and Kanye.
