Has na na na changed or am i tweaking?

so it started yesterday and i was listening to nanana when it felt kinda...different.the vocals felt turned up.so i pulled up the music video and i just know thats not how dr death defying sounded.he didnt have an accent im sure bcs normally i loved his talking but this accent just annoyed me.also im sure the lyrics to look alive,sunshine went "its 109 in the clock" and not "109 in the sky".i also remember the censorship in nanana mv being subtle but it doesnt feel that way rn.I might be wrong with all of these,but i know something changed in Look Alive,Sunshine.Is this a mandela effect?did anyone else notice this?
