I actually intended a different thing, but of course also what you says applies. What I meant is for the technical side of it, not the art involved. Pictures do indeed age, what stays and make them timeless (eventually) is the quality of the art involved and the emotions they convey and provoke, be it for nostalgia reason or whatever. Same applies to music, you may have a beep or a full binaural orchestral composition, but in the end what will stick with you is the tune in itself and what it raises in you, not by how many strings it has been played. Different tastes for different people of course.So yes it's true the music won't age - if you stick on graphics.
