Bjork will only let certain people cover her songs.
The 'Mutual Core' singer chooses artists she thinks will do a fresh take on her tracks to record their own versions.
She said: ''I'm in a protected situation. I've already done my version the way I want it to be. I ask people I already like, it's not like I'm asking just anybody.
''I like the remix platform. There are invisible rules but a lot of freedom.''
Bjork also said she'd like to work with dubstep star Skrillex, adding to NME magazine: ''The dubstep sounds appeals to me. I like it because it's quite prankster-like, it's trying to surprise you.
''I bumped into Skrillex at a festival. We did talk about maybe doing remixes, so I don't know, but sometimes after a few drinks there's a lot of talk.''
