Rapper Juice WRLD has been sued by members of rock group Yellowcard for copyright infringement over his hit single "Lucid Dreams."

According to a complaint obtained by Billboard, former Yellowcard members William Ryan Key, Peter Michael Mosely, Longineu Warren Parsons, and Sean Michael Wellman-Mackin allege Juice WLRD and his collaborators copied "melodic elements" from their 2006 song "Holly Wood Died" without permission. 

The group now want damages to the tune of $15 million and a "running royalty and/or ownership share" on all future exploitations related to the song or, alternatively, statutory damages "for each act of copyright infringement" and for defendants to be "permanently enjoined" from exploiting "Lucid Dreams" in the future.

Moreover, plaintiffs claim that in addition to recording revenue, they are owed damages from Juice WRLD's concert tours and other public appearances given that the "overwhelming success" of "Lucid Dreams" launched the rapper's career and provided him "substantial opportunities to tour and perform around the world."

Yellowcard's attorney, Richard Busch, released a statement to the outlet about the complaint:

"This was not a lawsuit the guys wanted to file. They put all of the parties on notice a long while ago and gave them every opportunity to try to resolve it. That notice was pretty much ignored leaving them with no real choice. As alleged in the complaint, this is not just a generic Emo Rap song, but is a blatant copy of significant original compositional elements of Holly Wood Died in several respects. Beyond that, everything we have to say is in the complaint."

$15 million may be a little steep. Reportedly the rapper is only worth a third of that amount.
