You can use Spotify Connect to play music on your TV, speaker, or gaming console using your phone as a remote.
Step 1: Connect both your phone and the other device (TV/speaker) to the same Wi-Fi network.
Step 2: Open Spotify on your phone and play a song.
Step 3: Tap the Device Icon (looks like a speaker and monitor) at the bottom of the screen.
Step 4: Select your device from the list.
Note: If you see a PIN code on your TV screen, go to spotify.com/pair on your phone or computer and enter the PIN to connect.
