Meanwhile, Tidal's revenue rose to 402 million Swedish kronor ($47 million) from 309 million kronor ($36.2 million) over the same period.
A person familiar with the matter told the WSJ that this financial statement doesn't reflect all of Tidal's U.S. revenue and financing.
According to Norwegian business publication Dagens Naeringsliv, which analyzed Aspiro AB's accounts, at its time of publishing on Monday the company was delinquent on payments to about 100 labels and owed $438,000 in unpaid bills.

Tidal's spending went mostly towards record label royalty fees, accounting for nearly 300 million Swedish kronor ($35 million) of the budget. Otherwise, 218 million Swedish kronor ($25.5 million) was spent on the company's 86-person workforce -- up from 77.2 million kronor ($9 million) in 2014.
It's been a big year for Tidal, as the company has released exclusive albums from Beyonce, Kanye West and Rihanna -- all of whom are co-owners in the company. In June, Tidal said it had grown its subscriber base to 4.2 million -- substantial growth from the 540,000 it had when it launched in the U.S. in March last year. Still, it lags behind the industry leaders Spotify's 30 million paying subscribers and Apple Music's 17 million.
Tidal did not respond to Billboard's request for comment.
