Most art in stores is just filling space on a wall to bring things together visually. I don't know that anyone cares about it communicating anything other than "the space looks less empty and more appealing for the customer". I don't think the average store owner is thinking any harder than that on it. I guess my point being we're mostly subjected to it based on the perspective we will like it and its cheap.
I think my point is, that the expectation of the people placing the thing for us to view/listen to and our own can be mismatched. I've always viewed the shitty pop in department stores as an imposition on my ears and I've never spared a thought for most wall art in a random cafe, but I imagine the owners are hoping to get something out of it from us. Whether thats satisfaction or manipulating us to spend idk.
