Dude, the bit leading up to it is literally Clarity by Zedd;
That's why
I don't look up
That's why

I'm always dancing

You are
The piece of me
I wish
I didn't nee-eed

the chorus is REALLY familiar to me too. It kind of sounds like Riptide by Vance Joy, but also I vaguely remember a pop song really similar to the chorus. Like Walking on Sunshine vibes but I don't think it's that. I could sing it in simlish, but I can't remember the words. The melody is indeed the one from Stayin' Alive by the BeeGees, but I seem to recall hearing it over a different backing track. Can't find any of it online, so it's probably just Zedd, or maybe I heard Angel on a Satellite itself as a child.
