What is the most popular song in history?<|im_end|>
<|im_start|>assistant
There is no definitive way to determine the single most popular song in history. Some songs that could lay claim to being one of the most popular include:

• "The Macarena" by Los Del Rio - A huge hit in 1996, "The Macarena" spent 14 weeks at #1 on the Billboard Hot 100. It's one of the best-selling singles of all time with over 50 million copies sold.

• "Candle in the Wind 1997" by Elton John - Elton John's tribute single to Princess Diana became one of the best-selling singles ever, with 33 million copies sold. It topped charts in multiple countries for many weeks.

• "The Twist" by Chubby Checker - "The Twist" popularized a new dance craze in the early 1960s and reached #1 in 1960 and again in 1962. It may have sold over 50 million copies, making it possibly the best-selling single ever.

• "Smooth" by Santana featuring Rob Thomas - The Latin/rock fusion of "Smooth" spent over a month at #1 on the Billboard Hot 100 in 1999. It won three Grammys and sold over 20 million copies worldwide.

There are many other contenders as well, from songs like "I Gotta Feeling" by The Black Eyed Peas to "My Heart Will Go On" by Celine Dion. Due to the challenges of tracking sales and chart performance over a long period of time and across countries, there may never be universal agreement on the single most popular song in history. It ultimately comes down to how you define popularity and how far back in time you look.<|im_end|>

It is difficult to determine the least popular song in history, as there are many songs that have been released over time and some may have never gained significant recognition or popularity. It is also important to note that popularity is subjective and can vary greatly across different regions, cultures, and time periods. Some songs may have been released with little promotion or distribution, while others may have received negative attention for controversial or offensive content. Therefore, it is difficult to pinpoint a single least popular song in history.<|im_end|>
