Spotify is 16/44.1 so the button should be red. Your source (Android?) is upsampling. Please read the third post of this thread for information about upsampling and why it's better to feed the Mojo a bit perfect signal. Or search the thread for upsampling, you'll likely get hundreds of hits as it's been covered hundreds of times.
Um, Spotify isn't 16/44.1 to the best of my knowledge. Only TIDAL streaming is CD quality (in the US at least). Which is why I pay extra for it.
