Rapper 50 Cent is being sued for knowingly sampling a riff without permission.
The star released the track for free a few years ago, thinking that he would be immune to legal dispute if he didn't make any money from it, according to TMZ.
However, Robert Poindexter of The Persuaders is filing a lawsuit regardless, after his band's song 'Love Gonna Pack Up And Walk Out' was used on his song called 'Redrum'.
He says in the suit: "Fifty Cents [sic] has not denied the infringement, but appears to be basing his defense solely on a frivolous and immaterial claim that the illegal version is not being commercially exploited, but is given away for free."
He is allegedly suing for $600,000 for punitive damages, plus interest.
