Jay Z, who paid US$56 million for Tidal's technology in January and relaunched it in March, went on the offensive against the supposed smear campaign.
Tidal has potential rivals including popular streaming service Spotify and tech giant Apple, though Jay Z did not post any details about the alleged campaign.
After Tidal was criticised because of the wealth of its founders, the rapper said that other big tech companies also have huge amounts of money.
On Sunday Page Six claimed that there's also a "war" looming between Tidal and Apple.
Citing industry sources, the New York Post's gossip site alleged that tech giant Apple is trying to impede Tidal ahead of the scheduled relaunch in June of its own Beats Music by taking a long time to approve iOS updates for the Tidal app.
