"Thanks to the Beatles, music in America became all about how to market sugar-coated garbage to teeny-boppers"
Ah, but they were doing that in the 50's/early 60's BEFORE the Beatles with Pat Boone, Bobby Rydell, Bobby Darin, Gene Pitney, Paul Anka, Dion, etc, etc
Agreed. However, with the success of the Beatles, it seems to me that it became a lot more commonplace and a lot more blatant...
