A Serbian singer has claimed that the hit 2014 song 'Uptown Funk' copied some of her material.

Snezana Miskovic is quoted by the Mirror as saying she feels the Mark Ronson and Bruno Mars track has taken too much influence from tunes she recorded with Aska in 1984.

The tracks in question include the song 'Ulice Mracne Nisu Za Devojke'.

The 56 year old, whose stage name is Viktorija, is threatening to sue for plagiarism.

The singer said: "Their song 'Uptown Funk' contains 80 percent of my tracks. How much of it are you allowed to take as inspiration for your song?

"I'm in no hurry to sue them, these processes take a long time, and my life and career does not depend on lawsuits.

"For these lawsuits, there should be a lot of money, the lawyers are working on a percentage. If I still decide to sue them and I win, I have to figure out what to do with that money."
