Contrary to popular belief, the immensely popular "Uptown Funk" is not a Bruno Mars song; it's a Mark Ronson song. And back in 2016, he was sued three times by various bands for jacking their tracks. An '80s girl band named The Sequence claimed Mark copied their 1979 song "Funk You Up." Another '80s funk band called Collage also threw their hats into the legal pool, and not to be left out, Roger and Zapp, who produced the ‘80s classic “More Bounce to the Ounce,” also decided to sue. Considering “Uptown Funk” was inspired by old funk music, obviously the inspiration would have to come from somewhere, right?

To date, two out of three of the lawsuits were settled out of court. Turns out having a hit song can be a costly legal liability.
