The fact that humans can make music that other species enjoy makes me believe in our inherent goodness
When I put on certain types of music, I can tell my cat really enjoys it. He closes his eyes and listens closely. He mostly likes very swelling music and beautiful, slow singing voices (like Judee Sill or Anna von Hausswolff) but also stuff like black metal and classical music.
The fact that another species can appreciate our kind of beauty the way we can appreciate theirs makes me believe in the inherent goodness of humanity, rather than us being an evil species.
