A few months ago I went down to the jacuzzi to sooth my aching back. I was startled to hear beautiful, ethereal music coming out of it. A couple of (young) teenage girls were singing a song in harmony, with a strong, beautiful melody and unisons, thirds, fifths and sixths weaving in and out, evidently making use of the natural reverb of the concrete and tile. I couldn't quite make out the words. It was exquisite. They stopped as soon as they saw me, unfortunately. I've never heard anything quite like it again.
Turns out it was a Beyonce song, something I wouldn't spend two seconds on if I heard it on the radio.
Context is important.
