No setup needed
Spotify works with IKANDY out of the box. Press play in Spotify and IKANDY follows.
Spotify
Spotify plays through Windows media controls, the same lane as any modern media app. IKANDY picks up track info, album art when the app publishes it, and the transport controls Windows exposes: play, pause, and skip. Per-Process Capture can lock the visuals onto Spotify's audio alone. There is no sign-in, no developer app, and no keys; IKANDY has no Spotify account integration.
Came here from an older build or guide?
Earlier builds offered a separate Spotify connection with a Client ID setup, and this page documented it. That integration has been removed. Nothing is required from you: play in Spotify and IKANDY follows automatically. If IKANDY does not react, see the audio sources guide.
