> If they haven't figured out how to turn a profit now will they ever?

The corporate entity Spotify will never turn a major profit, but that's by design.

Spotify made a deal with the devil to come to terms with the record labels, and is now fully baked into a "Hollywood Accounting" set of terms (https://en.wikipedia.org/wiki/Hollywood_accounting) which ensure the real money goes to the power players of RIAA cartel.

It turns out, if you have good lawyers, you can structure a set of entities such that neither the artists nor the public shareholders of the streaming service get the money, but rather, the opaque production company or record label that sits in between it all.
