Because of all the threads being made of late for 'artists with the most whatever' on Billboard, I decided to do one for a MUCH more accurate chart, the ARC Top 40.
Artists with the most #1 hits this decade (2000-2009):
Christina Aguilera- 6

Destiny's Child- 6
Beyoncé- 6
Justin Timberlake- 6
Rihanna- 6
J-Lo- 5
Avril Lavigne- 5
Alicia Keys- 4
Nelly- 4
P!nk- 4
Timbaland- 4
Chris Brown- 4
Britney Spears- 3 (She had 2 in 1999

)
Janet Jackson- 3
Usher- 3
Madonna- 3
Gwen Stefani- 3
Mariah Carey- 3
Kelly Clarkson- 3
Pussycat Dolls- 3
Nelly Furtado- 3
Eventually I'll do one with the most charted songs this decade. I'm sure we ALL know who that'll be.
Oh and if any of you little idiots try to add Destiny's Child's to Beyoncé's numbers, I'll report you.
Obviously she doesn't even need it.
