What was the song that ushered in the Gen-Z era of music?

What is your opinion on this? Many people pinpoint Lorde's "Royals" as being the song that shifted the pendulum away from the Millennials, but I've personally never agreed with it. I tend to think people overstate the influence that it had on Top-40 music at the time. For starters, electropop had already been declining in chart presence by the time "Royals" first debuted on the charts back in April 2013. Music in general was much more minimalist and acoustic-driven than it had been just a couple of years prior. Case in point, Passenger's "Let Her Go" was a chart-topping global hit at that time, while indie and EDM songs such as "Ho Hey", "I Could Be The One" and "Can't Hold Us" were occupying the Top-20 as well. 



I'm personally of the belief that "Black Beatles" was the song that truly kickstarted Gen Z's reign in music. Not only was this song a mega-hit in it's own right, but it also spawned the Mannequin Challenge fad and solidified Trap's presence in the Top-40 mainstream. I know personally this was the first song which made me feel as though I wasn't in the core target-audience for the music. "Black Beatles" was particularly popular with the kids in the younger years (Classes 2020-2021), but besides participating in the Mannequin Challenge (which is something people of all ages did), people in my year group never really got into the music itself.
