Not interfaced for Apple Music?

I dont understand why I cant get the full functionality of Apple Music on this. All I want to do is play music from Apple Music on my computer controlling it from my phone using the Apple Music interface already on my phone... how hard would that be? I can use airplay to control the Apple TV but not for my computer? Why? Apple is all about connectivity but if I cant just use the music app to control where the music is playing then they are way behind..
