Don’t understand graph. is dark line what people think of songs released 11 years ago? WTH is graph before age 0? Oh ok, maybe. A song released when you were 40 is rated the same as one released 45-80 years earlier.

There is huge bias in “popular music” category. Can get very sick of old songs, or just stop listening to contemporary pop after a while. I’m surprised old people would still like pop songs of their youth, after being overplayed over the years.
