Trigger Warning, Millennials: Gen Z Knows None of Your Favorite Songs

The growing battle between Millennials and Gen Z has a new point of belligerence thanks to a viral TikTok challenge where users reveal whether they know or don't know classic songs from the '00s. And while the over-25 set likely knows every song and can vividly recall bopping along to them at school dances and parties, Gen Z clearly doesn't see them for the classics they are.

In one video that blew up on TikTok and drew tons of astonishment from folks on Twitter, some tweens and teens didn't know a single one of these jams, from Destiny's Child's "Say My Name" to 50 Cent's "In Da Club." They were equally bewildered by TI and Rihanna's "Live Your Life" and Jay-Z's "Young Forever."

Some commenters actually refuse to believe they really don't know a single of the songs on the playlist. "I was born in 2002 I knew all of them there is no way you don't know these songs it's probably a joke," wrote one skeptic.

"Y'all definitely know these songs just posting this for clout huh it's okay," wrote another, as many pointed out the girl in the back is bopping along to the beat and seems to know the songs but won't budge over to the "know" side.

Others blame the parents. "Who raised you?" asked several commenters, and even some Gen Z folks said they knew several of the songs, which topped the charts in the aughts. 

A few people decided to react in videos of their own, like one guy who split screen with the pair of Zoomers and simultaneously grooved along to the hits while reacting incredulously to the youngsters' cluelessness until he finally had to walk away in disgust.

Well, the folks who insisted they couldn't be for real were right. The girls in the original post shared a follow-up where they not only knew the songs but were able to lip-sync along to pretty much every one. 

But plenty of others from their decade only knew half at best and insist if you know more than six of them "you're old." 

The disrespect.
