It’s a radio channel and all they play all day, every day is…go on, have a guess!
I listened for ten minutes this morning but I have to have it quite loud otherwise the noise from the birds in our back garden tends to drown it out.
It drives the cat nuts as well. I caught her trying to get into the dishwasher, either because she thought that’s where the bird song was coming from, or because she has actually gone mad and it was a suicide bid.
Perhaps they’ll broadcast other sounds as well, like whales crashing onto the beach, or cats singing, or that shuffling noise made by people queuing in the Post Office.
Add the smell of sweaty clothes and hair gel and you can actually believe you’re there.
