I can’t think of a song chorus or a phrase that has endured in the last decade. If it was a gameshow question to complete the lines from these contemporary songs how many would struggle?
seriously though, if you think a healthy music industry is a valuable thing for a culture, it's actually better if old stuff does not endure because it creates openings for new, young, living artists. There is great boredom in the world of classical music at the constant repetition of Bach, Beethoven and Mozart. They've been decomposing for many multiples of the years they were composing.
(side note: I'm not saying there's no sexism in Hollywood, but a similar case can be made for one aspect of their sexist practices: pushing older actresses aside creates more roles for a greater number of new actresses, more women get employed overall (weighted by the number of male vs female roles overall). Up and coming male actors get stifled by the dominance of already existing stars.)
