Kelly Clarkson's 2004 hit "Since U Been Gone" is a song we've all heard a million times, right? And it's a tune we could all sing if somebody asked ... right?
Well, somebody asked.
In a segment that aired on "The Tonight Show" Monday, host Jimmy Fallon gathered together an unusual assortment of singers and non-singers alike, gave them noise-canceling headphones and turned them loose on Clarkson's hit.
They couldn't hear themselves, and the results are pretty great.

We start off with Clarkson, who obviously nails it. (Though we're still not sure if she can sing it backward.)

But then we get Shaquille O'Neal, "Marvelous Mrs. Maisel" star Rachel Brosnahan, "Last Week Tonight's" John Oliver, The Roots members, Meghan Trainor, Mumford & Sons and "Black-ish" star Anthony Anderson.
The results are ... mixed. Trainor showcased some nice vibrato, while others like Oliver get an A for effort.

But totally epic!
And major points to the non-singers in the group, who totally get into it and remind us exactly what we probably sound like when we rock out in our cars.
