There's certainly a bit of that. Years ago, I had various generative musicish on my phone that I'd listen to (e.g. https://endel.iohttps://en.wikipedia.org/wiki/Endel_(app) ). There are also some soundtracks that are ok to listen to on repeat (though once you start recognizing what's next, then they become less useful because you can start listening to them - sim city https://youtu.be/j6mQc-9vCuE and eve online - looking now I see people have remixed that to 8h long tracks). I've also supported My Noise ( https://mynoise.nethttps://news.ycombinator.com/item?id=32366075 ) and have some 1h long tracks that I can put on repeat (love the white noise rain, but gotta give a callout to 88 keys with some slider adjustments to get it "right" for what I want - https://mynoise.net/NoiseMachines/acousticPianoSoundscapeGen... most often equal parts brown, red, orange and light purple).
But yea... I want a soundscape and it doesn't bother me if it was something that was generative in 2018, or in 2026... or loops of recorded sound... I want something that isn't silence and that I can not listen to for four to eight hours... bonus if its enough "noise" that it doesn't even get picked up after noise suppression in a Teams call.
