Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
This isn't the Kidz Bop version. The high voice is just because of the Nightcoring. Based on the acoustic guitar I figure it is probably a version done by a YouTube musician.
no, a lot of YouTubers censor bad words, they have young audiences and some just don't like to swear. Kidz Bop version doesn't change to acoustic guitar, they keep the saxophone and everything. This is clearly one person singing, whereas Kidz Bop is a bunch of kids. "Freaking" is too bad of a word too, they use "really awesome" instead. Honestly it baffles me that you could think it was Kidz Bop when it so obviously isn't.
