In music, Beyoncé is reigning over everyone, just like she does 10 years later in 2017. Avril Lavigne releases her third and most successful album. Rihanna and Chris Brown top the charts and make the news as one of the hottest couples of the year.
Revisit all of 2000's biggest hits with a full list of the Hot 100 chart-toppers here:
1. Beyoncé, "Irreplaceable"
Kicking off the year is Beyoncé's second single from her 2006 B'Day album. Beyoncé sings about unfaithfulness and female empowerment—a message that still permeates her music a decade later.
2. Nelly Furtado, "Say It Right"
Furtado's most successful record, "Say It Right," is a collaboration with Timbaland and Danja that was inspired by Eurythmics' "Here Comes The Rain Again."
3. Justin Timberlake, "What Goes around... Comes around"
Another chart-topper about betrayal and forgiveness, the song was Timberlake's third consecutive hit.
4. Mims, "This Is Why I'm Hot"
Mims' only Number One hit, "This Is why I'm Hot" shot to the top detailing why the Manhattan-born rapper is so damn hot in each major US city.
5. Fergie Featuring Ludacris, "Glamorous"
Recorded for Fergie's debut album, "Glamorous" describes a superstar who manages to stay grounded despite the success—one wonders if Fergie is sharing a personal story.
6. Akon, "Don't Matter"
Akon's first-ever number one song in the US was released in January, yet reached the top position only in April sampling Bob Marley's "Zimbabwe" and R.Kelly's "Ignition (Remix)".
7. Timbaland Featuring Nelly Furtado & Justin Timberlake, "Give It To Me"
"Give It To Me" is Nelly Furtado's second hit of the year. Featured on Timbaland's album Shock Value, it dominated club dance floors throughout the summer.
8. Avril Lavigne, "Girlfriend"
Avril's first and last number one hit, "Girlfriend" is a fun and quirky song to match the Canadian singer's image on her third album The Best Damn Thing. Its success was unmatched by later releases, although Lavigne is promising the drop of her sixth studio album by the end of 2017.
9. Maroon 5, "Makes Me Wonder"
The song is the band's biggest hit until "Moves Like Jagger" hit in 2011.
10. T-Pain Featuring Yung Joc, "Buy U A Drank (Shawty Snappin')"
Exploring the emerging culture of forming relationships in clubs and bars, T-Pain hits the jackpot, as the song becomes his first chart-topper.
11. Rihanna Featuring Jay-Z, "Umbrella"
One of Rihanna's biggest hits to date, "Umbrella" helps her transition from island girl to world dominating force of nature.
12. Plain White T's, "Hey There Delilah"
Released in 2006, the song takes a year to reach the top and another year to become a Grammy Award nominee.
13. Sean Kingston, "Beautiful Girls"
The debut single of Sean Kingston "Beautiful Girls" is a playful reggae track that is now considered to be the musician's signature song.
14. Fergie, "Big Girls Don't Cry"
Fergie's second number one hit of the year, the song is less hip-hop and more acoustic than the previous tracks from Fergie's album The Duchess. "Big Girls Don't Cry" also enjoys the most commercial success out of all Fergie's releases to date.
15. Soulja Boy, "Crank That (Soulja Boy)"
Soulja Boy's debut single hit the top of the charts and the commercial success of the record is unmatched by any later release.
16. Chris Brown Featuring T-Pain, "Kiss Kiss"
Chris Brown, then Rihanna's boyfriend, reaches the coveted number one spot after his girlfriend with a "lovey-dovey" rap song that's about getting a woman's (perhaps Rihanna's?) attention.
17. Alicia Keys, "No One"
"No One" was Alicia Keys' second (and last to date) chart-topper. The latest hit by the singer was in collaboration with Nicki Minaj in 2012 ("Girl On Fire" never made it into Top 10).
