I was discussing a time travel premise, where someone from our time finds themselves say in 1980, and how they would manage. Some people seem to think it obvious that such a traveler could, if they had good musical memory, become rich/famous by selling very popular tunes that haven't been invented yet. Specifically, "take "Oops! I did it again", repackage with more appropriate lyrics, and you're set". Similarly, if you travel from 1970s to say 1930s, just "write" the Beatles' songs.
To me, on the other hand, it seems reasonable that very popular songs would sound weird, off-putting, maybe even cacophonic 30 or 40 years before. Somehow the collective musical consciousness is not ready for them, the collective ear has not been prepared for such harmonies/melodies, etc. That's what I'm telling myself.
But, as a musical layman, I realize that I don't really know. The above sounds convincing to me, but what if it's just a plausible story I'm telling myself? Is there a more convincing argument for or against the claim that songs by the Beatles would be very popular, had they suddenly appeared in the 1930s, or Britney Spears' songs would be a sensation in 1980?
(I'm sorry if this question is too speculative)
