While listening to an "American Top 40" countdown from December 1970 on SiriusXM recently, my brother found the stylistic clashes between songs amusing. His amusement was well-founded, considering that Led Zeppelin's "Immigrant Song" and Perry Como's "It's Impossible" were in the same countdown that week.
With such "Never the twain shall meet" conflicts on the chart, a generation gap was inevitable.
