Of course, both Pandora and Spotify are losing a lot of money each year. Considering the financial situation of their costs, which don't go down the more subscribers they get, they will just be losing even more money.
I've been saying for some time now, that in the long run, the only companies that will survive in the retail music market are Apple, Amazon, Google and possibly Facebook, if they're interested, and also, possibly, Microsoft.
There has never been a successful music streaming company since the very beginning back around the year 2000. The only way it works is if there's a parent company that absorbs the costs out of other profit centers, because it believes that it benefits those other profit centers in their own sales and profits.
So those companies I mentioned can easily afford the several hundred million a year in losses both Pandora and Spotify are suffering. But neither Pandora nor Spotify can, in the long run.
I think this is pretty bad. As you said, none of the current music streaming ventures are profitable. Spotify is not profitable, and neither is the Apple Music division of Apple. The difference is that companies like Apple have the deep pockets to maintain unprofitable divisions long enough to build market share and then jack up the prices. It's a strategy straight from Walmart's playbook: match low prices until the competitors are gone, then when your customers have no other choice, turn them upside down and shake. Do people really think that Apple Music will remain $10/month after Tidal, Spotify, and Pandora are out of business?
