No one has posted here, so I will .... I just listened to the village bell tower ring 10 times and am listening to my fan humming with windows open.
They have long YouTube tracks of nature sounds that are quite relaxing. I don't know the names of them (as they are often amateur created), but I've put some on as background music before. Some are hours long and work for certain moods. Very relaxing.
Yes, I got some free audible books from Google play. Some have all nature type sounds like waves on the ocean and water running, rain etc. They are interesting..... I like to have my windows open and listen to the brook running out back....only this time of year with the spring thaw. I also hear robins, blue jays, chickadees and woodpeckers!!
I will eventually start listening to classical music again.
I listened (woke at 2:21 a.m.) to Audible books free version of Drift off.. bedtime stories by Joanne D'Amico. Never went back to sleep. It was nice to listen to. I will try more audible books. I didn't think I would enjoy it.There are quite a few. Amazon has an audible plus free trial..I should try that. One thing I noticed if you use the free trial...there isn't much to choose from. Everything I wanted to listen to cost a lot of money.
