There's a new YouTube video called "Do Teens Know '90s Music". It's on a YouTube channel run by The Fine Brothers called React.

They're the guys who do the YouTube series "Kids React", where they show kids outdated things like VCR's, and see if they can guess what they are.

In this one, they have ten teenagers listen to seven different songs from the '90s, just to see how many they know.

The songs are: "The Sign" by Ace of Base; Sober" by Tool; "Basket Case" by Green Day; "Gangsta's Paradise"by Coolio; "One Sweet Day" by Mariah Carey; "Tubthumping" by Chumbawumba .

And "I Want It That Way" by The Backstreet Boys, which is the only one they all recognize.  Probably because it's BARELY a '90s song.  It came out in 1999.
