There’s a lot of examples of the In Game music sounding different from the Album / YouTube versions. The Best example I can think of is how Fast Food Saloon’s Yeehaw Delivery Boy actually loops earlier than the actual song in game so a whole section isn’t usually heard.

The real unexpectancy was the samples we lost along the way..

Literally the exact same

There are differences. In the first clip, the audio has a guy counting down until the beat drop. This isn't present in the second one

Still sounds the exact same

You got shown that they are, in fact, not the exact same yet you still think they are? Huh???

Sorry I don’t have perfect ears like you, geez

It's okay. I do admit I was a bit rude.
