Pop music is a genre of popular music that originated in its modern form in the United States and United Kingdom during the mid-1950s.

If you ever listen to pop music the radio, you’re probably at least familiar with the concept of weekly pop music charts. They often play as a countdown of either the top five or top ten songs on the chart that week and either samples or the entire songs are played.

Pop music is hard to ignore and even if you absolutely hate it. There’s a pretty sure chance that you have heard at least some of the songs on the charts. Pop music is everywhere and it’s a mixed bag of awful racket and some genuinely interesting songs. That all somehow reach the zenith of popularity.

While some songs may only be on the chart for one week, there are others which remain among the most popular songs for months on end. This, after all, is how we judge the most influential bands and musicians – if a song remains on the charts for a long period of time, there’s a good chance that your grandchildren will know it too.

It’s no trivial matter that names like The Beatles and Elvis Presley both found their way at the top of the charts for several sustained periods.
