I'm making sure, just in case, but the categories like "2015 Number 1 Singles" do include singles with number 1s that aren't on day one? I couldn't really tell from what was already in those kinds of categories, and it /seems/ fairly straightforward. For instance, only Wonderful World / Ça va ? Ça va ? was in 2015 Number 1 Singles, and I added the others that had reached #1 at any time, but only The Middle Management ~Josei Chuukan Kanrishoku~ / Gamusha LIFE / Tsugi no Kado wo Magare hit #1 on day one.
