This was the year the biggest pop stars got their first No. 1 hits and lots of hitmakers were younger than 21 years old. But what is your absolute favorite song of 2019?
Ariana Grande, Jonas Brothers, Selena Gomez and Shawn Mendes are in a long-running league of their own by earning their career-first Billboard Hot 100 chart-topping singles just this year. The JoBros have spent 12 years on the chart with 21 entries total, Gomez has spent 10 years with 29 entries, Mendes has spent five years with 13 songs, and Grande has spent five years with 50 songs. Mendes scored his home run with girlfriend and frequent collaborator Camila Cabello for "Señorita," while Grande notched not one, but two No. 1s in 2019: "Thank U, Next" and "7 Rings."
