I don't really listen to Kidz Bop, nor have I ever liked it.
If you want my opinion, I think it's utter garbage.
I don't get the point of "kid-proofing" songs, and getting rid of bad words, because even if the curse words are removed, hints, undertones, and themes of the so-called "inappropriate things" in the song/songs are still there.
Sure, you can "kid-proof" songs for children, but eventually, the bubble placed around them will break (metaphorically speaking), and it's only a matter of time before they find out the truth for themselves. (Sorry if this turned into a super long rant, lol).
