This was like when they released the "Can you dig it?" end credits song for Iron Man 3 and a lot of people were like "...what the heck is this???" It sounded like a cheesy 80s tv show, but it still contained the main theme. Same thing here. I'm sure we hear Giacchino's Doctor Strange theme in this released track, but it has been stylized as a 70s homage for the end credits. I'm sure the main score will be as grand and "other-worldly" as you guys want it and expect it to be.
