Perhaps we need to differentiate between "end products" and "intermediate products". Cloth/fabric is an intermediate product. You use it to make things to sell, so increasing its production while decreasing human labor input is net beneficial, since it increases demand for jobs downstream of the supply chain. Music and art are enjoyed as end products, though. There hasn't been an industry-wide supply chain shortage of music since the invention of the record player (an invention that took music to the consumers, increasing demand from artists).
