| There's a multiplicity of factors, really. For example, take the most recent entry on this list, "One More Night" by Maroon 5. For seven of its nine weeks at number one, it held "Gangnam Style" in the runner-up position on the strength of its massive radio airplay, despite coming second to "Gangnam Style" in sales for most of the weeks they monopolised the top of the Hot 100. The formula that's presently used to calculate the chart is a factor, and it's only one of many. |
