It would be wrong to think that the word "pop" is a simple abbreviation of the term "popular music", although their root is the same. Popular music existed before the pop business. I tend to refer to popular music everything that, for one reason or another, became known to almost all listeners, regardless of their degree of preparedness and the type of music itself. This is what has gained recognition of the masses, people, population (from the Latin word "popularis" - folk, useful to the people)...
