The music business is failing to understand the power of streaming, as witnessed by their use of exclusive releases, that is, releasing material on one service only. The immediate reaction to that was a huge spike in piracy. People, rightfully, don't want to pay for multiple streaming services just so they can listen a particular artist. Recently, Kanye West released his new album on Tidal only, with a grand announcement that it would only be on Tidal. It was massively pirated. So, quickly, it was released on other services. It was a dumb move from the beginning, and shows that the business (and some artists) just don't get it.
There will be consolidation in the industry and it's not really clear how the services will differentiate themselves. Audio quality will converge as bandwidth issues continue to resolve.
But I don't know anyone that wants to pay for multiple streaming services, unless there is a real distinction - and I don't know what that is (but maybe Daniel Ek does!).
Anyway, I've collected music for 40 years and really like knowing that it is my music and won't be affected by a service going out of business, an artist pulling their catalog from the service, or an internet outage, or some DRM scheme being broken. It's a nice way to check out new music and find artists I didn't know about (e.g., spotify playlists). But I can still play LPs I bought 40 years ago, along with DATs, CDs, and digital downloads.
