We recommend strongly that you use your Spotify app.  All family members and guests can easily connect the network music player to their Spotify apps on their own phones, tablets or computers.

Be sure that you have a Spotify premium account - if you don't, get it here. You will really enjoy the premium account. It offers high quality audio, plays any song anywhere, is totally ad free and has unlimited skips. You can listen offline as well which is a great feature, and maybe most important of all - you can stream Spotify to the network music streamer over Wi-Fi.

The music is directly streamed from Spotify's servers to the network music streamer - leaving your phone free for making calls and all other uses. You only use your phone to control music playback. You can also just pick up the music where you left off when switching between your phone, tablet or computer. It is seamless streaming. 

The streamer's network device name is Player - choose Player as a device.
