A lawsuit is filed against Bruno Mars and Mark Ronson in federal court in California on Friday alleges that tune of their hit track “Uptown Funk” sounds extremely similar to funk Group College’s 1983 single “Young girl”

“These acts of infringement were willful, knowing, malicious and perpetrated without regard to the Plaintiffs’ rights,” the lawsuit reads.

According to Pitchfork, the band Collage claims “many of the main instrumental attributes and themes of Uptown Funk are deliberately and clearly copied from Young Girls.”

“Uptown Funk,” released in 2014, was a huge hit for Mars and Ronson, but also the subject of multiple copyright controversies. In addition to the current lawsuit, three members of The Gap Band were added as songwriters due to the song’s alleged similarities to The Gap Band’s “Oops! Upside Your Head.”
