Heyo! I've been doing that other thread for about a year now so I thought I could share some more of the data I've extracted from it. Not sure what that could be in the future, but for now I'm looking at the biggest hits on the chart. For this, I enlisted some help from Innocent Eyes a while back to get a good rough sales average to work with, given that the positions on this chart tend to equate to similar positions on iTunes week after week (for instance, #30 on the unofficial chart is usually around #200 on iTunes). The week's #1 scores about 1200 points, while #100 scores about 100. For the time being, I'm weighting all weeks the same. If I were to change it, there'd be a lot more Christmas & Prince songs for instance, whose real sales don't quite get justice here, but for now I'm just keeping it consistent.
However I probably won't keep the posting schedule consistent so we'll see how that goes
In case you were wondering, the only #1 hits to miss the top 200 are the ones that only charted for one week. Jon English's "Six Ribbons", Michael Jackson's "Thriller" and Kate Bush's "Wuthering Heights" are tied for #211. We'll see only 2 more #1s before reaching the top 100.
It's been a while but it's time for the 2017 update to this list! Same point system is in place, but with twice as much data to digest. I've made the effort to divide the stats into separate years, so as I count this down, I can tell you how many points were scored in each year*. For interest's sakes, when I've finished counting this down, I will try to construct a table so you can see what the top 200 would look like including only the last 52 weeks of data.
*I will refer to Oct '15 to Oct '16 as 2016, and Oct '16 to Oct '17 as 2017, for simplicity
