it’s jarring to me see them so close to the top and over songs in my view are much better and suit this forum’s tastes much more.
I can see where you're coming from. Ballroom Extravangaza would not have survived this rate back in the early days of the sub-forum, as it seems very antithetical to what people liked K-Pop for. However, the reality is we've lost so many users to the abyss and gained a few others from different sub-forums, that you could argue its survival is reflective of the sub-forum's current taste.
Of course, the majority agree on a few things like balladphobia because this is still PJ after all, but the general makeup of voters in these rates has changed so much that we're all bound to come at these things differently (and I say this as someone who gave Ballroom Extravangaza a relatively high score).
