My time machine is broken and the only parts won't be available until 2035, so I can't really tell you much about the state of the arts in 2075

) (please take that as honest humor!)
Like I said I am in my late 50's and haven't stopped looking for new talent, art, etc. Since music is the topic, I listen to on the radio not only classic rock, as would be expected at my age, but current as well. There is a station out of Jax, FL X102 that plays excellent current rock. But then collecting I go the other direction, to music before I was born. I like a lot of turn on the 20th century what was called Folk that later was the basis of much of the blues and early country. I love old blue grass, jump blues, big band, and dance band stuff (though I was old enough to hear a lot of dance band stuff as it came out).
My kid that just died, we used to listen to the radio at work in the kitchen. Again all my kids accused me of not liking current music and being stuck on classic rock, and it still surprises them when I turn up a current song and start singing.
I don't want to say Rap or Heavy Metal isn't an art form, far be it from that, but I just didn't like those eras/genres. For my subjective likes and dislikes I have picked and chosen artists and genres through all the history of recorded music I have found.
I don't care for classical, though I can listen to Bach Fugues most of the day. I don't like Jazz if it gets to esoteric, but more of a cool and smooth jazz person. I don't like country genre much, but there are several country artists that are excellent, Roy Clark, Earl Scrugs, Gretchen Wilson, Johny Cash, are examples of country I love.
But I totally understand the point of being stuck in an era. I was like that for long time following the late 60's and early 70's music. I didn't understand at that age and time the influences that led the artists of then to their compositions. It wasn't until decades later that I studied the origins, and started loving more music from current to before I was born.
