I do find it interesting that so many songs from this period persist despite their age and relative obscurity in everyday life.

For example, with the exception of Mariah Carey's Indestructable #1 song, the holiday 100 [1] are predominantly from the 50s and 60s.

I'd love to understand why this is - the Lindy Effect just describes it, doesn't really explain it.
