This is the Introduction of the Unreal Roller Coaster Ride Remix.
The intro should be soothing, yet somewhat haunting, then it gets bumpy, all of a sudden something never seen just hit you, then some more bumps, and finally, the ending, where you leave in a different place than which you came from.
This song has a hip-hop feel, but the middle changes slightly.
Please contact me if you would like to use this in a project. We can discuss the details.
