By any economic standard, the demand for art of all forms is skyrocketing, as you can tell from the price of opera tickets, by the number of books sold, by the number of books published, the number of musical titles released, the number of new albums and so on.
按任何经济标准， 对所有形式的艺术的需求 正在飞涨， 从歌剧票价， 图书销售量， 出版的图书数量， 发行的音乐剧数量， 以及新专辑的数量等等都能看得出来。
