[TOMT] Mostly quiet YouTube background track with a couple trumpet notes and a few Mario-esque notes

Seems to come up regularly in Youtube video essays and the like, for instance around 7 minutes on this Whang video: https://www.youtube.com/watch?v=mnMRXZQLL_U

Next to impossible to find without being in video credits, and it never really makes it to the credits or description. Anyone know what the background track is called?
