Hi Matthew,
You can pull off that effect using 3D Serpentine. To do this, create the path of the rollercoaster in After Effects using a small Solid Layer. Keyframe the position to create the path. Then, apply 3D Serpentine to a Comp-Sized Solid and set the path layer as the extrude path. This will create the 3D path. You can then set the body to Line, and you will get a thin strip. By adding an image with the transparent background and the music notes as the Body map, you should be able to pull off the effect you're going for.
To try 3D Serpentine as a demo, go to
