The theme song for 'The Fiend' Bray Wyatt has rapidly climbed up the music charts, just days after it's release to the public.

As of writing, the song by hardcore Punk band Code Orange is sitting at #2 on the iTunes charts and #26 on the overall top 200 songs on the service.

The theme is currently ranked #29 on Amazon's Best Sellers In Albums chart and #48 on the Best Sellers In Songs chart.

Wyatt, who returned to the ring at SummerSlam with a victory over Finn Balor, has become one of the hottest stars in wrestling, thanks to the new Fiend character.

WWE touted the success of the song with the following statement: 

Yowie wowie! "Let Me In," the signature theme of The Fiend that debuted this past Sunday night at SummerSlam, is already spider-walking its way up the iTunes charts.

As of Thursday night, the haunting tune by Orange Theory is at No. 26 on iTunes, and has surpassed such songs as "If I Can't Have You" by Shawn Mendes, "Sober" by TOOL and "ME!" by Taylor Swift in the rankings. Something tells us that Bray Wyatt's diabolical alter ego is just starting to overtake the world of music.
