I think in 90% of the galleries I've been in the I'm expecting the art to be communicating something so I'm inferring intent or making my own, but by itself art is a poor communication medium imo. So much so we often say it's about whatever YOU perceive from it. Obviously artists set out to invoke --something-- and we accept that and at least some of us try to think on it, but the person perceiving the art is really doing a lot of work to fill in the gaps. Expectations here are aligned.
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.
