Pink, Lil' Kim, Mya and Christina Aguilera perform "Lady Marmalade" at the 2001 MTV Movie Awards at the Shrine Auditorium in Los Angeles.

We'll breakdown 2001, but you can relive all the Hot 100's number one hits year by year:

The year is 2001. A gallon of gas costs $1.46, Wikipedia launches, Apple releases the first iPod, and The Fellowship of the Ring kicks off the Lord of the Rings film series. 

The September 11 attacks shake the nation and wake Americans to the threat of terror attacks on a global scale, while fears over anthrax in the mail have Americans on edge. Meanwhile, the Enron Corporation is embroiled in charges of corporate fraud and corruption, legendary racing driver Dale Earnhardt dies in a last-lap crash during the Daytona 500, and U.S. President George W. Bush refuses to sign the Kyoto Agreement on Climate Change. 

In music, Janet Jackson dominates with her seventh studio album, All for You, and its title track, which topped the Billboard Hot 100 for seven weeks. Otherwise, Destiny's Child teaches us a new word, "Bootylicious," Alicia Keys makes her debut with the hit single "Fallin'," Jamaican-born Shaggy turns the pop market onto his reggae swagger and a little song called "Butterfly" by Crazy Town flutters onto the charts. 

Revisit all of 2001's biggest hits with a full list of the Hot 100 chart-toppers here: 

Destiny's Child, "Independent Women Part I"
The hit song was first featured on the Charlie's Angels movie soundtrack before its release on Destiny's Child's Survivor album.

Shaggy feat. Ricardo "RikRok" Ducent, "It Wasn't Me"
The Jamaican-born former U.S. marine broke into pop music with his catchy ode to denial.

OutKast, "Ms. Jackson"
Unlike Shaggy, Andre 3000 and Big Boi were ready to fully address their actions on this Stankonia hit, which was inspired by Andre's relationship with Erykah Badu and her mother.

Joe feat. Mystikal, "Stutter"
R&B singer Joe's only chart-topper as the lead artist reached No. 1 with the help of a remix featured in the comedy Double Take.

Crazy Town, "Butterfly"
The hit was the third single off Crazy Town's The Gift of Game debut album and flew to the top with the help of a sample from the Red Hot Chili Peppers' "Pretty Little Ditty."

Shaggy feat. Rayvon, "Angel"
Another No. 1 for Shaggy! The second single off his Hot Shot album strikes a more romantic tone using elements of Steve Miller's "The Joker" and the classic hit "Angel of the Morning."

Janet Jackson, "All for You"
The year's longest reign atop the Hot 100 belonged to Janet Jackson's All for You title track, which made radio history by becoming the first song rack up adds on every pop, rhythmic and urban radio format in its first week of release.

Christina Aguilera, Lil' Kim, Mya & Pink, "Lady Marmalade"
This star-studded hit cover of a song originally recorded in 1974 by the group Eleventh Hour (and made popular by Labelle) was recorded for the Moulin Rouge! soundtrack and spent five weeks in the top position.

Usher, "U Remind Me"
The Jimmy Jam and Terry Lewis-produced single was the first off Usher's 8701 album and later won the singer his first Grammy Award for Best Male R&B Vocal Performance.

Destiny's Child, "Bootylicious"
The second single from Destiny's Child's Survivor album featured prominent sample from the 1981 Stevie Nicks song "Edge of Seventeen," which was co-signed with Nicks' appearance in the video.

Alicia Keys, "Fallin'"
The debut single off Alicia Keys' debut album Songs in A Minor, the breakout hit won three Grammy Awards and delivered a new star to music.

Jennifer Lopez feat. Ja Rule, "I'm Real"
This remix was featured on a re-issue of Lopez's J.Lo album, making the helping breath some more life into the entertainer's sophomore set, which remains her most successful album to date.

Mary J. Blige, "Family Affair"
The Dr. Dre-produced track spent six weeks at No. 1 and remains Blige's only chart-topper to date.

Usher, "U Got It Bad"
The second chart-topper of the year for Usher, who was 2001's only solo male act to lead the Hot 100.

Nickelback, "How You Remind Me"
The lead single from Nickelback's third album, Silver Side Up, is the Canadian rock band's most popular song and only Hot 100 No. 1 to date.
