Time for an oddly-specific, possibly poorly explained musical question:
For you, what song has the highest correlation between you personally loving it, and its popularity?
To be clear, I don't want you favourite of all of the most popular songs. I want the most popular of your favourite songs.
A nerdier interpretation: if every song had a rating for 1-100 of "how much you love it", and also a 1-100 rating of "how popular you perceive it to be", I want to know the song that gets the highest combined score, out of 200.
Or, if the X axis is "how much you love the song" and popularity is the Y axis, the one that's at the top-right of the graph.
I think you get it....
