Refrigerator hums more beautifully than birdsong today

As I was sitting in meditation this morning: the near constant hum of refrigerator was in contrast to the fervent songs of birds outside doing their mating and communicating. It occurred to me that my refrigerator was more useful to me than their piercing cries, as I closed the window to be more focused within. It was a revelation in that I have usually preferenced the sounds of "nature" (water, wind, birds) over modern culture (machine sounds of various sorts), but that on closer inspection, I might just have well thought the opposite given the respective sound-making entities' function in my daily life. Certainly, the world needs birds and their songs for no other reason than biological diversity and their inherent beauty and worth. However, that humming refrigerator keeps my food fresh for days, saving me from a trip (in my exhaust and noise spewing car) to the coolers at the grocery store every day. To me, today, closing the window on the birds doing their own things, for their own sakes, allowed me to appreciate the refrigerator doing its own thing and me doing mine as well.
