Without exclusive deals (which I absolutely hate) the differentiation between streaming music providers is price and quality of user experience. Tidal's claim is the lossless quality of their music; however, the reality is unless you are streaming through a dedicated amplifier and expensive headphones/speakers 99.9% of users will never be able to tell the difference between a Tidal stream and a Spotify stream. A set of Beats headphones hooked up to a smartphone is going to sound pretty poor simply because of the power limitations of the DAC chip.
I'm all for competition. Tidal can either step up its game and provide a service a sufficient number of users are willing to pay for or they can shut down. Even Microsoft couldn't make it work and is shutting down its Groove music subscription service at the end of the year. I just don't think they will be able to compete with Spotify, Pandora, Apple, and Amazon.
