The background music of the trailer for The Chronicles of Narnia 3: The Voyage of the Dawn Treader is that "Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh"

Wait a minute, I have one

[00:07-00:23]"Prologue (Through the Wall)" —— Ilan Eshkeri ("Stardust OST")

[00:24-00:35]"Magical Mystery" —— Brand X Music

[00:40-01:18]"Glory and Honor" —— Two Steps From Hell

[01:19-01:53]"Heart of Courage" —— Two Steps From Hell
