Regardless whether you prefer jazz, pop or baroque - does it matter whether the cassette tape you first heard a certain melody on was TDK or Sony brand? Or, for that matter, whether it was FM radio, a record or a CD?
I get what you mean and this is an aside, but speaking from a psychological standpoint, it might actually be of high importance, if the memory was very early in your life and pivotal with the first time you connected to music in a meaningful way.
For example, I've tried to analyze why I like the look of film so much, and I think a lot of it comes down to how much I saw of it as a child. At school they'd take us to the library and project film reels from the 60s and 70s. Every picture I saw in a magazine was on film and using the techniques that worked with film.
The brain has an odd way of hanging on to things that originally formed its base.
Back to your point. Consider the sculptures in St. Peter's Basilica. You can be blown away by the artistry, which comes from the artist knowing the human form, being able to communicate intense, meaningful emotion through it. Or you can appreciate the material used, the way that the marble some seems soft and glowing and human even though it's a stone. I did both simultaneously and the experience was unforgettable to me - which I did not expect. "What is it": A) it's beautiful marble. B) it's condensed human experience. C) it's the height of achievement in artistic technique. D) all of the above.
Discussion of the work itself typically doesn't go much past "Cool" or "I like it." So there's a thumbs-up feature for that.
Typically yes. Once in a while, something stops you and catches your breath. That can be someone else's work or the photo you yourself are about to take appearing in your viewfinder. "Cool" or "I like it" would seem comically, disrespectfully, irreverently insufficient for those rare moments.
And something has to be said for the realm of words and the realm of pictures occupying a different container of experience. This must be part of why description of pictures with words is often not suitable.
