Comment on Today I found out about blinking LEDs

There are also LEDs with a built-in “candle flicker” effect. This teardown shows how it’s done with two dies integrate into the LED package: the LED and an ASIC. They also demo a circuit using a small flicker LED and an amplifier to control a much larger LED.

Is it true, or just a myth, that some of those cheap plastic votive candlelights actually use the same IC/circuit as musical greeting cards in order to flicker (that is, they’re ‘playing’ some song to the LED instead of a speaker)? I forget where I heard that but thought it was a clever hack if true.
