One of the most accurate measures of a song's popularity is how many times it has been viewed on YouTube; once a video reaches one billion views, you can be sure it is one of the most well-known songs ever. Only two videos could claim to have received more than a billion views at the beginning of 2015. Ten additional people had passed the mark by the end of the year. In a few more years, several of the pop tunes 2021 supplied would become instant hits, quickly reaching the billion-selling mark and beyond.

As of 2022, many videos have reached the one billion watch milestone, with many more coming close. For instance, you'd assume Puff Daddy's song "Been Around the World" would be on this list, yet it only has a paltry 5.5 million views! A few giants that have easily surpassed the billion point—many of which have tripled it—sit at the top of this popularity pyramid. These are not underappreciated songs; instead, they are all too popular sentimental songs. Are you able to identify them?

Probably, but just for fun, here are the top 5 songs on YouTube in the entire world.
