A new investigative report by the Norwegian newspaper Dagens Næringsliv alleges that TIDAL deliberately inflated streaming numbers for Beyoncé’s album Lemonade and Kanye West’s The Life of Pablo by hundreds of millions of plays, as Music Business Worldwide and the French news agency Agence France-Presse report. TIDAL has denied the claims, calling it a “smear campaign.”

According to MBW, reporters from DN obtained a hard drive that allegedly contained manipulated TIDAL streaming data. DN took its findings to Norwegian University of Science and Technology (NTNU)’s Center for Cyber and Information Security (CCIS), which analyzed it and produced a study.

DN reports that the study found over 320 million false plays of Lemonade and TLOP songs, affecting over 1.7 million users, according to the AFP. Alleged false plays include, for example, one user who played TLOP tracks 96 times within one day, with 54 of them coming in the middle of the night, according to the report. The data also reportedly shows users “listening” to multiple songs at once, according to MBW. In addition, tracks were reportedly played at suspiciously precise intervals—every six minutes, down to the second and millisecond.

Music Business Worldwide states that DN accessed TIDAL’s record company royalty payment reports, which show that, in April and May 2016, the platform paid Sony $2.5 million for Lemonade streams; in February and March 2016, TIDAL allegedly paid Universal around $2.3 million in royalties for TLOP streams.

Both Lemonade and The Life of Pablo were released exclusively on TIDAL in 2016. While TLOP was a six-week exclusive on the JAY-Z-owned streaming service, Lemonade is still available to stream only at TIDAL. In March 2016, TIDAL announced that TLOP was streamed 250 million times in its first 10 days after release. In May 2016, just over two weeks after Lemonade’s release, The New York Times reported that Beyoncé’s album received 306 million global streams.

TIDAL sent the following statement to Pitchfork:

This is a smear campaign from a publication that once referred to our employee as an “Israeli Intelligence officer” and our owner as a “crack dealer.” We expect nothing less from them than this ridiculous story, lies and falsehoods. The information was stolen and manipulated and we will fight these claims vigorously.

According to Variety, the “Israeli Intelligence officer” and “crack dealer” comments were made in previous Dagens Næringsliv stories about TIDAL, referring to TIDAL COO Lior Tibon and Jay-Z, respectively.

Dagens Næringsliv has published multiple reports on TIDAL. In January 2017, the newspaper alleged that TIDAL was inflating subscriber numbers. Then, in December 2017, DN reported that TIDAL lost NOK$368 million (around $44 million) before taxes in 2016. In response, a TIDAL spokesperson said, “We have experienced negative stories about Tidal since its inception and we have done nothing but grow the business each year,” according to The Verge.
