The battles with the 6 of the 8 Sanctuary Guardians (Seriously) and some common enemies has some of the most calming and funkiest boss music I have ever heard. It basically goes hand-in-hand with the Video Drugs (The battle background) as its calm and focused just like how you would need to focus actual psychic powers, which is what your team needs to use. Also very big props to this OC remix version.

I've also doodled one of the Guardians here.
