From Anap to Furnunculus and Langlock to Reducio, those Hogwarts kids had their work cut out for them mastering every spell in the book.

But one guy –  a Muggle, no less – has managed to incorporate almost every single spell into a rap, and YouTube officially has a new hero.

Alex Day uploaded the impressive footage on Monday, and since then the clicks have been going through the roof.

After sharing the words of the rap with YouTube users, Alex realised he had accidentally omitted Levicorpus, and used Mobilicorpus twice.

"I was devastated whe I realised," he wrote, but it doesn't look like anyone is holding it against him as thousands have flocked to the page to check out the performance.

 "Holy sh*t, everything about this is perfect," wrote one while another YouTube user added: "This is simply the best thing that happened today."

Ladies, prepare yourselves for this one.
