Fun fact, some LED candles just use such a cheap chip connected to a LED instead of a speaker, so they'll flicker... they'll flicker the song all along.

Short datasheet for the curious.

the part numbering in the datasheet makes it look like there were dozens of different songs at one point, since they're numbered like -001, -002, -019, -068. I wonder what their full catalog looked like?
