2018 gathered from the front page, 2016 from a sheet Aday had put together, and 2014 from the not very scientific method of going through each page and counting instances of "week $" which created a bit of a mess from people who like to name their songs after each week - hopefully picked up most of these. Let me know if I fucked it up or you have a better way of confirming numbers.
I hapazardly tried to update the image with recent stats for 2018; I don't have access to the stats from previous years and by editing a new graph on top of the old graph image it won't be 100% correct (I think my line ends up being a bit too high relative to its actual number), but it gives a good idea I think?
neat! i wonder if we came out on top this year ahead of the rest for total numbers!
