I want to know the answer to the following question:
What type of music was used in traditional mass?
All the background I'm provided with is that "Further experimentation with the new Mass by liturgists, such as the usage of pop/folk music (as opposed to the Gregorian Chant advocated by Pope Pius X), along with concurrent changes in the order of sanctuaries, was viewed by some as vandalism.". Is that enough to answer the question?
