Singer Bjork has slammed long-standing reports alleging instrumentals for her 2001 album Vespertine were written by engineer Valgeir Sigurosson, insisting she composed them herself.

The Icelandic pop star blasted the claims in an open letter to local music paper Reykjavik Grapevine, after her album was referenced in an interview with hip-hop/electronica DJ B Ruff.

In the article, the DJ talked about "Bjork's voice mingling with Valgeir Sigurosson's instrumentals" - and the comments riled the star so much, she felt compelled to write in and set the record straight. And Bjork recalls a previous incident involving Sri Lankan rapper M.I.A. to prove her point about the difficulties faced by women in the music industry.

She says in the letter: "M.I.A. had to deal with this with Pitchfork.com, where they assumed Diplo had produced all of her Kala album without reading the credit-list. It just had to be - it couldn't have been M.I.A. herself! It feels like still today after all these years people cannot imagine that women can write, arrange or produce electronic music. I have had this experience many times that the work I do on the computer gets credited to whatever male was in 10-metre radius."

"One thing that could have kept this misunderstanding alive is that neither me nor Valgeir Sigurosson have bothered to correct it. But I am doing it now."
