The catchy tune Agatha All Along" from WandaVision is now available on music streaming services, including iTunes and Spotify. It was featured in the seventh episode, titled "Breaking the Fourth Wall," and played at the end of the show after the season's latest big reveal.

Fans were treated to the revelation that Wanda is not the only magical person in the town she's supposedly been controlling. It was revealed that her neighbor Agnes is actually Agatha Harkness, an archetypal witch, Wanda's mentor, and occasional villain from the Marvel comics. In true WandaVision style, the reveal was driven home with a sitcom-styled ditty that fans can now enjoy over and over again.

Fans wanting to replay WandaVision's grand revelation can now download the song, featuring a vocal contribution by Kathryn Hahn, on Spotify, iTunes and other music streaming services. The lyrics of the song indicate that Agatha is actually the villain of the show and that, "It's too late to fix anything."

Who’s been messing up everything?

It’s been Agatha all along!

Who’s been pulling every evil string?

It’s been Agatha all along!

She’s insidious

(Ha-ha!)

So perfidious

That you haven’t even noticed

And the pity is

(The pity is, pity pity pity pity)

It’s too late to fix anything

Now that everything has gone wrong

Thanks to Agatha

(Ha!)

Naughty Agatha!

It’s been Agatha all along!

And I killed Sparky, too!

Whether Agatha's meddling can be undone or will simply help transition into another Marvel Cinematic Universe movie is yet to be revealed.
