Sounds I love to hear.

Nicely put, Vinny.
I like to listen to the bees and small insects working away in the flowers
The rustle of leaves in a light breeze
The scrunch of dead leaves beneath my feet
The song of the robin above my head
The song thrush who is always in the same couple of trees at the end of the garden
The sheep on the hillside, especially when the lambs are with them.
I stop whatever I'm doing to watch a buzzard riding the thermal, the Air Ambulance helicopter as its heads to the hospital, a dragonfly hovering over the pond and a rainbow!
My scent of the moment is Cow Parsley, almost as "tall" or "short" as I am, flowers at head height inline with my nose.

I've never understood people I see out walking, ears blocked by headphones or whatever they're called now, oblivious to the sounds of the world around them. There is no more beautiful music than the sound of nature.
