Video: This Taylor Swift-Harry Potter mashup has the Internet exploding from joy

If there was ever a video designed to make the Internet explode from joy, this is it.

Los Angeles actress and self-described “Harry Potter superfan” Kate Parkin posted a video on YouTube featuring a medley of Taylor Swift songs reworked with Hogwarts-related lyrics and sung from the point of view of J.K. Rowling characters Hermione Granger, Ron Weasley, Draco Malfoy, Luna Lovegood and, of course, the boy wizard himself.

“On the train I took a seat,” the song starts off, “I said, ‘Your lightning bolt’s on fleek.’” And it gets even nerdier from there.

Parkin’s song features the melodies of Swift’s hits “Shake It Off,” “Welcome to New York” (“Welcome to Hogwarts”), “Bad Blood” (“Mudblood”) and “Blank Space.” She makes her affection for her favorite character (her YouTube name is weasleysweaters) and Harry’s creator clear in the song: “Weasley’s the king, Rowling is our queen.”

The Internet has reacted predictably: with unalloyed glee. The video has been viewed over 100,000 times, with commenters barely able to control their happiness. A YouTube user with the Potter-related screen name LoonyLovely Luna wrote, “This. Was. AMAZING!!!!! Great job! I’m crying, now.... Imma go share it all over Facebook now....” Another commenter agreed, writing, “so bloody good; you’re one talented witch.”

Emma Lord, an editor at Bustle who describes herself as a “Hufflepuff, cupcake addict, and songwriter,” was also slightly enthusiastic, writing, “There are only two things I love in this world, and they are Taylor Swift and Harry Potter (sorry, family). But now there is a third thing that I love more than either of them.”

As Lord notes, this isn’t the first time Parkin has come up with a Hogwarts-related parody song. She reworked “Do You Want to Build a Snowman?” from the Disney film “Frozen” as “Do You Wanna Build a Horcrux?” and Katy Perry’s “Roar” as “Gryffindor.”

Parkin, elated at the video’s success, thanked her fans in a YouTube comment: “I am at a complete loss for words. SIRIUSLY who slipped Felix Felicis into my coffee this morning?”
