If I listen to upbeat music it definitely boosts my mood. But, I feel the reverse is a little more complicated.
When I listen to sad music and I’m feeling down, I honestly feel something different. Maybe not happiness, but contentment, because of shared experience.
A shared experience of pain or hardship with that artist that gives a different kind of fulfillment through understanding.
The problem for me is that if you abolish copyrights it means your creation can be used for any reason without permission.
Maybe you don’t care if somebody downloads your music for free to listen to or uses it in their goofy TikTok dance video.
But, no copyright also means the most terrible person on the planet can use your song at their political rally. They can use it as a backing tracks for ideals you do not agree with. A major corporation can use it in their advertising campaign. They can even straight up sell your creations as their own for profit.
Without the protection of copyright, artists, authors, musicians, video content creators, etc. have no say in how their work is used.
