While Jay Z has boasted that Tidal gives artists higher royalties than any other streaming service, a new lawsuit alleges that the company isn't always paying them.

In a class-action complaint filed on Saturday, John Emanuele of the band The American Dollar alleges that he has not yet received any royalties from the streaming service. In the same suit, the band's label, Yesh Music, alleges that it has only received reduced royalties from Tidal, accusing the streaming service of "deliberately miscalculating" per-stream royalty rates and diluting payments by "up to 35 percent."

Shortly after its launch in March of 2015, Tidal owner Jay Z said that the service "pays 75% royalty rate to ALL artists, writers and producers — not just the founding members on stage."

A Tidal executive later clarified that with Tidal, 62.5% of royalties goes to labels, while 12.5% goes to artists. She said that this still puts Tidal above industry royalty standards, which break down to 60% and 10%.

The lawsuit also alleges that Tidal failed to issue NOIs (Notice of Intent to Obtain Compulsory License) before including music on its service, which the complaint calls "part of an egregious, calculated, and ongoing campaign of deliberate copyright infringement."

The lawsuit was filed on behalf of Emanuele, Yesh and "all other similarly situated copyright holders." It demands between $30,000 and $150,000 for 118 copyright registrations.

In a statement to Mashable on Monday, a representative for Tidal said the company is "up to date on all royalties" for Emanuele's music, and said they have removed all music from Yesh Music, LLC, and John Emanuele. "They are misinformed as to who, if anyone, owes royalty payments to them," the statement reads. "As Yesh Music, LLC admits in their claim, TIDAL has the rights to the Master Recordings through its distributor Tunecore and have paid Tunecore in full for such exploitations. Their dispute appears to be over the mechanical licenses, which we are also up to date on payments via Harry Fox Agency our administrator of mechanical royalties."

The statement pointed out that the American Dollar's entire catalogue "streamed fewer than 13,000 times" over the past year.

"We have now removed all music associated with Yesh Music, LLC and John Emanuele from the service. This is the first we have heard of this dispute and Yesh Music, LLC should be engaging Harry Fox Agency if they believe they are owed the royalties claimed. They especially should not be naming S Carter Enterprises, LLC, which has nothing to do with Tidal. This claim serves as nothing other than a perfect example of why America needs Tort reform."

"Ironically, when Defendant CARTER purchased the TIDAL Music Service in 2015, it claimed it would be the first streaming service to pay the artists," the lawsuit reads. "Different owner, same game."

After its high-profile launch in March of 2015—attended by big-name stakeholders like Rihanna, Madonna, Kanye West and Nicki Minaj, all present to promote the image of an "artist-owned" business — the streaming service faced backlash from many less prominent artists.

Marcus Mumford shot back at Tidal last April, saying, "when they say it’s artist-owned, it’s owned by those rich, wealthy artists." Death Cab for Cutie's Ben Gibbard later expressed similar frustration, saying that Tidal focuses its energy on mega-famous super-earners rather than those "who are struggling to make a living in today's music industry."
