I am not sure if this kind of question is on-topic or not.
I just heard the soundtrack used in Scott Manley's recent video SpaceX Radarsat Launch Highlights (fairly quiet sound level) with the notes

I've set the two time cues for the videos to roughly analogous points.
Are these in fact two versions of the same music, or is the resemblance just a coincidence? Are there objective, unambiguous ways that the level of similarity can be measured? If so, how might they be applied in this case?
This one has a fairly quiet sound level:
