Kpop follow up

Hundreds and hundreds of songs later (youtube "korean top 100 2015-2008", for those who are interested, but I dont recommend it), I can't tell which part of the year I'm in. I mean, shouldn't the top 100 of year get progressively better as you count down? There isn't a discernible difference between the 79th to 69th songs and the 10th to the 1st place songs. For any year. I'm going to give up. The mystery song will never be rediscovered, which is too bad, because it was so many millions of times better than all the rest of Kpop that finding it would be like finding a Beatles song that was a million times better than every Beatles song you have ever heard. No, nevermind, I like the Rolling Stones better. But I like Black Sabbath most of all.
