If you had the power to broadcast sound directly into everyone's minds, everyone in the world simultaneously, what would it be? A message? In what language? A series of beeps and boops? Music?
You can do it as many times as you want, whenever you want. People hear it no matter what - be they deaf, sleeping, even if they have their head up their ass.
What would you broadcast?

What other superpower would you like to have the most?
