I played with it for fun ages ago, but not too seriously. I started learning the Piano something like 2? ish years ago, and it taught me enough about musical theory to be ... not very good at making music, but a lot about the structure and flow of music.
It can be difficult, because the language used to describe music is very different from the language we use to describe the physical world around us (some may disagree) but as an untrained (I wouldn't count my Piano lessons as formal music training) musical person, I can detect clearly the formulas that apps like suno use to construct arrangements.
Music is mostly patterns and mathematics. Where it gets exciting (to me, at least) - is when people have bonds over it.
I think a song about going to Mars isn't a very relatable concept for a lot of people, so a song like this would be difficult, from a subject matter perspective. That doesn't make it bad, just makes it more difficult for people to connect with the song in the way they might connect with something about heartbreak, or playing with a cat, or walking a dog, or other experiences that we've shared.
That probably isn't unique to music - its the same in fiction, art, movies, games.
