Even so, gaining 490,000 subscribers in six months is an achievement for this relatively small company, and Tidal’s high­-definition, lossless-audio option, which costs $20 per month, seems to be helping to differentiate it from peers:

Riley says 45 percent of new subscribers opt for lossless.

And from a purely financial standpoint, Jay Z, 45, may have already made his money back: $56 million was not a huge price for a fully functioning streaming service. He paid $110 per subscriber, a fraction of Spotify’s $425-per-subscriber valuation at its last funding round; Deezer is hoping its upcoming initial public stock offering will fetch up to $330 per revenue-generating subscriber.

and I said "low key successful"

45% of new users are paying $240 a year for lossless.. which is crazy IMO but I think Tidal is a niche app and doesn't need to rule the streaming world to make money.
