Listen to the song after the jump.

Amid an ethereal, electronic soundscape, Siri addresses Flaming Lips vocalist Wayne Coyne, saying, “Wayne, I don’t understand the moon, the stars and the sun.” She ends the dreamy song with, “Wayne. Now I understand.” Coyne posted the song on SoundCloud, calling it a “sound construction piece.” “Life is beautiful. Music gets you high,” he said.
