Very simple: Who is taking the time to sit in that one spot only and listen to music all around him/her?
Yeah, @ the beginning when it's new in our life we explore it and we enjoy some of those cool surround music.
But after approximately 15 years of sitting right in that sweet spot, it's time to move around and ride our horse, or go sailing, or fishing, or just have a picnic @ the beach under a tree by the ocean or a lake. ...You know...
@ home nowadays we cook, we do the laundry, we clean the yard, we get kids to school, we garden, we surf, we listen to the birds singing on our porch, we invite friends for brunch, we play bingo, we go bowling, we watch the news, we water the plants and the flowers, we shower more, we dust, we duck, we stay alert, we hug, we kiss, we talk, we look @ the sky, @ the view, @ what's outside, and we enjoy meditating, sleeping, dreaming, ... and music is playing, often, from our servers, our r.a.d.i.o.s, or stereos, our living rooms, our bedrooms, our studios, our libraries (we love to read too), our galleries, and all that jazz.
Nowadays, how many hours a day do you spent sitting in that hot spot and listening to multichannel music?
After ten years of doing that it's nice to do some' else, don't you think?
...Unless you are completely new to it, then you'd rather listen to your smartphone through headphones.
And unless you are an addict with no direction home.
