I want to know the answer to the following question:
Who did Beyoncé and Lady Gaga tie with for the most number one hits since 1992?
All the background I'm provided with is that "The song topped the US Pop Songs chart, becoming the sixth number-one for both Beyoncé and Gaga, tying them with Mariah Carey for most number-ones since the Nielsen Top 40 airplay chart launched in 1992.". Is that enough to answer the question?
