"This is sense gratification music"

In 1966 in New York City, a boy came by with a record of a famous Indian musician playing a sitar. As soon as the music began, Shrila Prabhupada started to smile. The boy asked, “Do you like this music?” Shrila Prabhupada said, “This is sense gratification music.” The boy was hurt and said, “What do you mean? They play this in the temples in India.” So Prabhupada insisted, “No, this is sense gratification music and this musician is just a businessman.” The boy then replied, “Well, you used to be a businessman.” Prabhupada laughed and said, “Because I went naked then, I should go naked now?”
“Well, what if this musician wanted to become a devotee?” asked the boy.
“Oh, that would be very nice,” said Prabhupada, “if he can come. But this is sense gratification music.”
