The 1.5 Mil increase is a good look for Jay, but it doesn't change the fact that it'll be virtually impossible for Jay to continue running Tidal for longer than a few more years.
Music licensing rights are over a billion dollars a year right now for streaming companies, and they're going to go WAY up in the near future since all the major labels feel they're getting ripped off currently. In order to survice in the streaming game, you've either gotta be able to operate for damn near a decade without seeing any profit. Spotify's been running for 7 years and hasn't made a profit yet. To last in music streaming, you gotta be a huge company with billions in profit coming in from other products, (Apple, Google, Amazon) or have billions invested in your company from multiple firms (Spotify has Goldman Sachs and Dubai Oil money out the ass invested in them).
I've said before I think Jay is gonna try to get his subscriber numbers up to around 5 million, then sell the company to Samsung. Even though he wouldn't own Tidal after that, that's still a major power move.
