I can give some insight to this. If you search for white/brown etc. noise on spotify for songs you won't find longer tracks. I use these while travelling if I'm having troubles sleeping in a room where there's noise, or on a plane. Airpods in, lie back and it blocks out more noise. The problem with the albums of white noise are they fade between different kinds of noise which usually only lasts a few mins - this is enough to break the effect. I can only presume there is a limit on song length for albums, because there are white noise podcasts which are 10 hours long - which is exactly what I need for my use-case.
