Help A Non-musically Gifted Gal Out! - Tumblr Posts

What is the audio in this clip?? Is it something I should recognize?? I don't understand why ANY of the tracks from D-Day weren't used...there's even Interlude:Dawn if they wanted instrumental only...Am I missing something? Wait it sounds like part of the beat for Snooze but with more added to the front? I'm so confused...I need someone that's better with music than I am. That sigh at the end is giving more RM and less SUGA as a producer to me though ...
