Yeah, crickets are actually soothing to listen to when you're relaxing outside after a long day. Somewhat similar to watching goldfish swim around in an aquarium. It actually reminds me of my youth, when I used to walk around in my yard at night collecting lightning bugs in a mason jar. Listening to the crickets rub their legs together, and walking closer to the sound, to try to see this in action.
This is so weird, just earlier tonight I was listening to crickets out my window and said to myself, I should record them. Alas, I did not. I always find a use for crickets in the shows I produce (umm… unfortunately - LOL). Cool. Still, it is very much a coincidence that you had the same thought today.
