Alien Culture

Alot of the GFL summits are all about us (humans). I want to know about alien culture. Do other cosmic species create music and art? Do they make movies and have concerts? Do they have their own entertainment industries and book authors? Do they have stand up comedians? If so, why can't they share that with us? Why don't they have their own youtube channels where they post their galactic top ten songs? We don't need their technology to given to us yet, but it would be cool to see a painting or hear a song from any cosmic species.
