A Canadian punk band's music is pressed on Beyonce's Lemonade vinyl by accident

Some Beyonce fans had a (noisy) surprise when they picked up a vinyl copy of her Lemonade album.

The US singer's music was missing from a small number of copies of the record and had been replaced with a punk band instead.

Five songs from Canadian group Zex had been pressed by mistake on to the first side of a limited edition yellow vinyl.

Fans expecting to hear Hold Up instead got songs by Zex, such as Child Soldier and Let Them In.

"I like to believe she's just a big supporter," Gretchen wrote.

A statement from Beyonce's record label blamed the vinyl problems on "human error" at a pressing plant in Germany.

"Beyonce and ZEX were not aware of or responsible for the mispress," said Columbia Records.

"Fans who purchased the vinyl will be refunded and given a replacement copy.

"We apologise for the inconvenience this has caused."

In a post on her Instagram account, Zex frontwoman Gretchen Steel said she hoped it wasn't a misprint and that Beyonce was just a fan of their music.

Beyonce hasn't commented on the misprint, but Zex posted a video of the vinyl playing their music on Facebook.

"Those of you who got the new Beyonce record Lemonade may be surprised to hear what will be playing on the A-side," they wrote.

Their fans are desperate to get hold of an incorrect copy, saying they'll be worth a lot of money in the future.

Zex are a four-piece band who formed in 2013.

They were dropped from their record label on Tuesday after it claimed to have received emails accusing guitarist Jo Capitalcide of sexual assault.

This is a photo of Gretchen Steel from her Instagram account.

In a statement, it said: "In light of ongoing and recent accounts of alleged sexual assault tied to Zex guitarist Jo Capitalcide, the routine boycotts of promoters, venues, and record stores when the band is booked or carried, and information shared first-hand by singer Gretchen Steel to the label about Jo's behaviour in their open relationship (which corroborates one of the accounts sent to the label by a survivor within the past 24 hours), Magic Bullet Records is hereby dropping Zex from its roster of artists, effective immediately."

However, in an interview with Pitchfork, Gretchen Steel denied the claims.

"All we know of these allegations is what is posted in the Magic Bullet statement.

"We have no information about the accusations made except for what was posted in the article. We have no further comment on this matter."
