“Yes, Western classical music (including liturgical music) is studied and performed more than any other music, and for good reason.”
Your answer applies to academia - an elitist institution to start with and ignores that the majority of “popular” musicians were neither trained in or studied classical music.
Your answer does not apply to what are most popular forms of music that are “performed”, which is all forms of “popular” music, not “classical” music, which is a fact demonstrated by “most often performed, as in has the most live, telecast and recorded performances” associated with it. And classical music, as much as I too enjoy it, simply does not have more performances where it is performed compared to performances of “popular” music in its many forms.
Like I said: Jeremy Bentham.
More people have heard of Beethoven than any single pop music figure.
