My money is on "some kinda will thingy like Haki, your haki is stronger than opponent, you knock him out. Otherwise, he resists."

Same thing here, thus when Bones executed the music during FI, its mainly aimed at the lower ranked soldiers. If it works on stronger people (Mihawk), then THATS overpowered. Speaking of which, itsn't that roughly the same as Apoo?
