Spotify vs. Apple Music vs. Google Play vs. Tidal: Which is Best

Tidal MQA is the best 192k/24bit music. much more detail and dynamic then sportify 320bps MP3.

For me, Spotify and it is not close. I use streaming exclusively for music discovery and Spotify is far better at that. If I like an album sufficiently to want to listen on unbridled quality, I buy it. 

I've never tried Spotify so can't say that Tidal is "better", but I chose Tidal because of the availability of Master quality albums.  I do almost all my Tidal listening on decent systems and can hear noticeable differences in sound quality when comparing most of the Master quality albums vs their "HI-FI" versions even when not using a MQA capable device.  I wish Tidal catered more to my musical tastes (classic rock, jazz, electronic) and was easier to browse by those categories, but I can usually find anything I want through the search function.  

Go with MUSCONV tool to sync music files from one music stream to other such as amazon music to google play, tidal to spotify,  itunes to spotify, and more..
