How to Sleep to Ambient Music

I've listened to music sleeping since I was a teenager probably since the mid 80s but back then I was listening to like knits or ebb and skinny puppy going to sleep. Now I do have a very specific like music can't have words and it can't have drums that's not to say every flight I take starts with Mark Hollis from Talk Talk solo record which has drums and singing. But at home when I'm going to bed at night yeah the music can't having vocals or drums drums just because tends to be you know a little more disruptive sounding in vocals.
