I've got a weird memory when it comes to pointless stuff, and I'm about 99% sure it came out between 4 and 5 central last year. Not sure about previous years but that'll be my official guess.
It came out mid day last year. I was at work in the middle of a client meeting and my phone started going crazy so I remember this vividly . It might not have come from Pitchfork directly (XRT might have leaked it early?) but the lineup was definitely out well before 5pm CST last year.
