Angie Stone has a gripe with Bruno Mars. She says years after “Uptown Funk” spent weeks at the top of the Billboard Hot 100 chart, she has yet to get paid for an interpolation from a song she did with her 1970s group that Mars used on the track. The singer/songwriter explained in a recent interview about Mars using a portion of her song with her group The Sequence on his 2014 hit with Mark Ronson. The Sequence even took the duo to court over the matter in 2017. The lawsuit, obtained by TMZ, claimed Mars and Ronson’s song has “significant and substantially similar compositional elements” to the 1979 song, “Funk You Up” from the rap trio.
