The end goal of music is to make art: to connect with others and the spirit of creativity and passion.
What is the end goal of a competition and battle of the bands? Do they still hold making art as the top priority?
If it’s just about how technical and fast you can play or how many people show up to support your band, is art even being considered a priority, let alone being made at competitions?
If it isn’t art, what is it? Skill? Popularity? It then seems more like a sporting event or a beauty pageant.
That doesn’t sound like music to me.
