First of all, I have never ever heard the first song ever used in an edit. Second of all, I'm gonna be using the audio used in each individual edit. Third of all, its a test video for an intro, a 5 sec part of holocene fit well with the slow motion.....it's 5 seconds not even close to a full song not even used in an edit. People have used this in many videos, music is repeated, it happens.
