There are The Beatles....and then there's everyone else.
My 4-yr-old granddaughter always a bundle of energy and a lover of music was climbing all over me, "Hey Papa, watch this!" And she will stop and sing songs from Frozen and some other Disney classics and a few pop songs she's heard. I was on Youtube and played a Beatles' tune...she stopped...and listened. Never uttered a sound, just stood by and listened. When the song ended, she smiled slightly and went about her busy business.
That says it all.
