I often wake in the early hours and need something to help me sleep.There are plenty of threads for baby sleep music, but I didn't see any for adults. I've tried soundtracks aimed as sleep aids, such as rain, white noise, relaxing musak, but end up lying there, relaxed in body, but mind active, thinking how awful they are. I've tried more general playlists like "peaceful piano" or gentle pop music but if I do start to drift off the changes in pace and pitch between the tunes can jolt me awake. If you have something that works reliably for you, what is it?
