I cannot confirm this, but I'm pretty convinced this background music loop is used by the Merry Maids to up their productivity. Enjoy these soothing sounds whether you're cleaning or not...its pretty awesome.
Admittedly, I wasn't always crazy about this loop. It took a few listens before it really grew on me...but now as I pass Finding Nemo and hear this ambient loop I get the feels for real. Love it.
