I hadn't added Google Music to restrict it to what I initially felt would be major players. I was trying to avoid adding every service that exists out there. TIDAL, Rdio etc
All of these music services include more or less the same functionality, music availability, and services. The argument that one service doesn't have "Artist x" doesn't really hold seeing as you can now include your own library on "Offline Mode" on Spotfiy and a similar feature in Google Music.
Also, as a student Spotify gives you half off, so it is more of a reason to purchase in my book.

I will likely not get Apple Music based on my experience with iTunes Match. Google will consistently stream as long as I have signal on my phone, and does a fantastic job of predictive buffering. iTunes Match on the other hand is basically unusable while driving and the vast majority of the time won't even start playing songs unless they have been downloaded ahead of time over wifi. Apple's infrastructure can't have gotten that much better in such a short time. I might give it a trial run, but honestly I'm not sure as I'm so happy with Google's product.
My family of five would cost $30/month on Spotify as compared to $15/month on Apple Music.
