This one has a bit of a story behind it. I submitted it to BuzzFeed while they were running their experiment of having a puzzle segment, and it was accepted for publication. I was stoked, because their crosswords, edited by the wonderful Caleb Madison, were damn good; the best constructors were submitting their work to BuzzFeed because it was a new, highly trafficked publication, and they also had some young 'uns such as myself who put some youthful verve on the grids, avoiding some of the mustiness of the New York Times. It was also less censorious than the Times, which appealed to me.
Unfortunately, this puzzle never saw the light of day because BuzzFeed nixed their crossword just months after starting it; it was a valiant effort, but I don't think regular BuzzFeed readers would ever embrace a cutting-edge crossword. I got the rights to it back, so here it is for your solving pleasure.
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 Kanye and myself.
