What is the song on the title screen of Dragon Ball Z: Resurrection 'F'? There is a song from the title screen from Resurrection F. I think it is in the Bluray version, but I'm trying to figure out what the name is.

Does anybody know what it is?
The title song for Resurrection 'F' is: "Z no Chikai" (a.k.a "Pledge of Z")
