The old Listen to the clouds page no longer loads reliably because its scripts have stopped working. The services themselves are still available, so this site now has a small replacement:
The music panel can play an embedded Spotify ambient playlist or AmbientMusicalGenre on SoundCloud. Choose either source from the menu, then start playback in the provider’s own player. It also retains a SomaFM station picker that opens the official SomaFM player.
SomaFM does not permit third-party embeds, so it stays in its official player. Enter an airport ICAO code, such as RJTT for Tokyo International Airport, then open LiveATC in a second tab. LiveATC availability varies by airport and may depend on its current access rules.
The page starts with Spotify Atmospheric Calm, SomaFM Drone Zone, and Tokyo International Airport as its defaults. Spotify, SoundCloud, SomaFM, and LiveATC remain the providers of their respective audio.
