How to get music playing from Zero and PhatDac

I have a raspberry pi zero w and have bought the Phat Dac from here.
I was hoping that I could use it to play music from my NAS server, but for now I loaded or copied a couple of music cd’s onto the zero’s sd card, and although the music would play, it was only for a few seconds or so for each mp3 track.

I installed both Audacious and pulseaudio to get this far.
Is there anything else I could or should do to get it working
