Playing what music you want depends on the options you have.
I have a Qnap NAS where all my music are stored and that's where my Bose Soundtouch are playing my music from.
Same with Google Music, upload your music and create your own playlists. Or pay a premium and listen to whatever music you want.

@fourthofjuly Do you know if it's possible to stream music from Google Home via Google Cast do the Soundtouch? If yes, is that possible without using the remote control - only by voice command?
