I want to bring Spotify to my house but I have some limitation:
I do not want to use Alexa or Google systems.
I do not want to use my smartphone.
I do not want to have tablets around my house.
The main idea is to have a small device, used only to play Spotify music in every room and this device can send music only to speakers in that room. One can select the music directly on the device, control sound and so on.
