Songs to sleep to?

I know this sounds ridiculous lol but I realized when trying to listen to death metal that it makes me sleepy, not in a bad way it's just has a similar effect to soft classical for example. Idk maybe it's like how coffee makes some people tired...

I was thinking about trying to make a longer sleep playlist but I'm not all that familiar with metal and so I'm looking for recommendations. Obviously not looking for "quiet" songs but preferably ones that don't have long bits of silence. Any sub genre is fine but I think I prefer death metal.
