Amazing Music Video...

Hi everyone!

I've often thought: "what better way to have a first post on a YouTube Forum than this awesome music video?"
Or maybe that's just now.

Anyway, I found this, which I think is amazing.
It's a cover of the Goyte song, but see if you can work out the unusual thing about it:

Somebody that I used to know - performed by Pentatonix - PTXOfficial


Did you notice?

Spoiler:

I thought this video was amazing, hence I shared it - what do you guys think?

Very wise first post, indeed.
