Today, popular songs (usually abreviated to 'Pop') are songs sung by 20th and 21st century popular artists, played frequently on radio stations, used in dance clubs and discothèques, and usually released as hit parade recordings on vinyl and compact disks, or as MP3 files down-loadable from the internet. They are written in the Popular Modern style.

In previous centuries, the term was used for what we now often describe as folk songs. They share the elements of simple melodies and harmonies with traditional folk songs, in many cases. However, today they are often accompanied by very loud percussion on every beat.

Who knows, in future centuries, which of today's pop songs will be remembered, and called 'folk songs'?
