Correct.

And also, "music" made by the planets (as opposed to music made by Gustav Holst) falls a bit into the category of "If a tree falls...". If you admit this, you would also have to include this, which is much older.... though not many people can actually hear it:

Here's some video footage of the 1969 Apollo 10 astronauts hearing the noise.

Various Artists - Them Dirty Blues (1989)

A five LP box set from Jass Records released in 1989 featuring various raunchy blues and jazz songs from the 1920's to the early 60's. The oldest song in the set is from 1924.

That is an apples to orange comparison. The sound of a tree falling in the wood produces a sound wave only lasting a few seconds. That is an infinitesimal amount of time compared to the planets which have been making experimental music for millions of years.

It's only experimental music to us. To the planets, their own noise is probably considered folk, while they consider the sounds of other planets to be world music.

If I download a file with the recording Thomas Edison made of Au Clair De Lune on it then burn it to a CD can that count?

No cause you be doing it to impress a bunch of strangers on the internet not cause you like it.

Little Drummer Boy (1958)

Oldest one I like:
Lady in Black by Uriah Heep (1971)

I mean like, how can anyone own sound, man? Like, are we enslaving music, dude?

The Bristol Sessions, I think.
