Breakthrough Evidence of the Beatle's Genius?

I have written other threads about my journey to discover and more fully appreciate the Beatles.

In a peculiar breakthrough for me, my first born, 7 month old son instantly stopped crying yesterday when I parked his stroller close to one of the monitors in my bedroom system and played Rocky Raccoon and others.

With every noise and voice in the mix, every different instrument, playfully sung wry lyrics, he seemed to turn his head and stare at the speaker, completely fascinated.

This was after a long day where nothing seemed to amuse him. Needless to say, I was very pleased and hope this bodes well for his future as an audiophile.

Has anyone else had success with the Beatles -- or any other particular artists or composers -- with fussy children? How do I keep this going?!?

Best wishes.
