Oh c'mon, Pop Songs chart is not really a significant chart. If you want to measure chart success, look at the Hot 100, Digital Songs, and Radio Songs charts. Not this stupid minor genre chart.

Wanna see who got the most weeks at #1 on Billboard's MAJOR charts?

Most weeks at #1
Hot 100 - Mariah Carey (79 weeks)
Radio Songs (Hot 100 Airplay) - Mariah Carey (93 weeks)
