Does anyone know where that music is coming from?

[Description: a video with screenshots from SE5 of Pmd sky. The first is a portal the rift to the future. Carmelldansen is playing muffled. Soft light emanates from the rift, pulsing along to the music. The scene shifts to the dark future, where Dusknoir and Grovyle lay passed out on the ground. The music is no longer muffled, and colorful lights flash with the music. /End description]
