Taylor Swift fans have been left bemused after a factory error pressed a batch of new vinyls with bizarre Nineties electro tracks instead of upbeat pop.

       Swifties, the name used to describe the singer’s die-hard supporters, rushed to buy Speak Now, a re-recorded version of her 2010 album of the same name.

       However, when pressing the needle to the vinyl for the first time, some were alarmed to hear recordings of obscure club songs with macabre spoken vocals.

       It appeared that Speak Now was mistakenly pressed with Happy Land, a compilation of Nineties songs put out by Above Board Distribution, a British label which has branded the mix-up a “delicate pressing blunder”.

       The error first came to light when Rachel Hunter, a British fan, posted her unboxing of Speak Now on TikTok.

       She expressed alarm that the songs Back To December and Sparks Fly, on the A-side, sounded very far removed from Swift’s ordinarily upbeat hits:

       What Ms Hunter heard was an 11-minute-long obscure electro track called True Romance by Thunderhead The Word By Eden, with Beat poetry rambling over the intense beat, including phrases such as “dancing organisms” and “freaking anxiety attacks”.

       On the B-side, Ms Hunter was confronted by a droning bass and the repeated refrain “There’s 70 billion people on Earth – where are they hiding?”

       This was taken from a similarly esoteric track called Soul Vine, performed by Cabaret Voltaire, the Sheffield electronic music duo.

       A song called Happy Land by Ultramarine, another electronic music duo, was also erroneously pressed onto the bright-pink Swift vinyl.

       Ms Hunter has since updated her followers to say that she has specifically wrapped her misprinted album and is “going to look after it”.

       Above Board Distribution suggested that the mistaken pressing could become a valuable rarity, stating on social media: “Keep your eyes peeled for this special edition.”

       In a tongue-in-cheek statement on Instagram, the label said: “Never in our wildest dreams could we imagine this situation.

       “While we know all too well this error was beyond our control, we sincerely hope anyone who received what is Not Taylor’s Version of the vinyl is enchanted by the blissful electronica.”

       Dan Hill, the founder of Above Board Distribution, told the Resident Advisor website: “I dunno what the hell has happened, but Taylor Swift’s records seem to have been mispressed with our album.

       “Swift fans on TikTok are calling it ‘the cursed version’. It’s a massive collision of worlds as the music featured is from such different musical spheres.

       “Mistakes happen all the time. We’ve certainly made a few. But I hope the fans enjoy their surprise mix of electronic music. I’m sure it’s going to be a Discogs [the record collection website] rare pressing classic in years to come.”

       Universal Music, the label through which Speak Now was released, said that there were “an extremely limited number of incorrectly pressed vinyl copies in circulation”, but added that the company had “addressed the issue”.

       It was believed that both record companies use the same French vinyl pressing business, MPO.
