With the new millennium came the rise in pop-punk bands – while emo broke into the mainstream.
The skateboard-riding, wallet-chain wearing band members had us jumping up and down with our mates and crying alone in our bedrooms.
And who can forget some of those crazy hairstyles.
While some bands have kept a high-profile and continued making the music we know and love, others have faded into obscurity.
There are also those who broke our hearts by splitting, but there have been some much-welcomed reunions over the years.
Here is a look at what the pop-punk stars of the noughties are up to now:
The most iconic group on this list, Green Day rose to fame in the 90s with breakthrough album Dookie and helped popularise punk rock in the US.
They had a slight decline in popularity by 2000, but stormed back to the top in 2004 with American Idiot, their first number one album.
Green Day, comprising of Billie Joe Armstrong, Mike Dirnt and Tre Cool, proved they could be loved by a new generation and have sold more than 85 million records worldwide.
The five time Grammy-award winning band even had a stage adaptation of American Idiot debut on Broadway in 2010.
They were also inducted into the Rock and Roll Hall of Fame in April 2015, which was the first year they were actually eligible.
Surprisingly, Green Day have managed to stay away from controversy over the years, but Armstrong hit the headlines in September 2012 with his epic rant at the iHeartRadio music festival.
Believing they were going to be kicked off after seeing a screen with “1 Minutes Left”, he stopped mid-performance to vent his anger, shouting: “You’re gonna give me one f***ing minute? You’ve gotta be f***ing kidding me!”
The singer told the stunned crowd he “was not Justin Bieber” then smashed his guitar when the screen went blank, while Dirnt also destroyed his bass.
Armstrong then gave a finger, threw down his microphone and walked off stage in Las Vegas.
Two days later a representative for the band apologised for the incident and admitted their set was not cut short.
Armstrong then checked into rehab, with his rep telling USA Today he was “seeking treatment for substance abuse.”
The band barely looked like they’ve changed since they formed in the late 80s and are still making music to this day.
Emerging from the Southern California punk scene in the early 90s, Blink-182 became one the most popular bands on the planet.
Known for their toilet humour and sexual jokes, the band really cemented their global icon status in 1999 with third album Enema of the State and in 2001 with Take Off Your Pants And Jacket.
However, all good things must come to and end and their fans were left devastated in 2005 when they went they broke up.
With split opinions on their new ‘mature’ direction and tensions over their gruelling schedule, it was announced they were going on an “indefinite hiatus”.
Tom DeLonge wanted to spend more time with his family and considered his bandmates’ priorities “mad, mad different,” – leading to his exit from the band.
While drummer Travis Barker later admitted a painkiller addiction left him feeling ‘borderline suicidal’ as he reached the lowest point of his life on an aborted tour of Australia in 2004.
“I was so addicted to Oxycodone, and I had a security that would actually sleep during the day and then stay up at night to make sure I was breathing. That was pretty pathetic,” he told Billboard in 2015.
“My bones were so brittle from so much painkiller use. I had this moment when I got to Europe for that tour where I really identified myself as a dumpster. And I wasn’t proud. I was scared.
“I had to call Mark [Hoppus, Blink-182 bandmate] and say, ‘Hey, man. I’m like borderline suicidal. I’m going crazy. I need to go home.’ Like not even one show had started. I’d been there two days. I hadn’t slept one day.”
In September 2008, Barker was one of only two survivors of a plane crash that killed four people, leaving him with third degree burns, PTSD and needing 16 surgeries.
After breaking up the band did not speak until 2008 – and announced their reunion on stage at the 2009 Grammy Awards.
Their second coming was very dysfunctional and DeLonge left again, with Alkaline Trio’s Matt Skiba replacing him.
Barker has also been romantically linked to Kourtney Kardashian, but has insisted they are just close friends.
“Kourtney’s like a dear friend. That’s it,’ Travis told People magazine in 2019.
“I mean, I love her to death. I love her family to death. But yeah, just friends.”
The band released topically named single ‘Quarantine’ in August this year, while DeLonge has gone on to develop an obsession with UFOs.
Bowling For Soup
Best known for singles High School Never Ends and Girl All the Bad Guys Want, Bowling for Soup entertained us with their catchy lyrics and humorous jokes.
Some fans might not realise that the band performs the intro theme tune to Disney Channel show Phineas and Ferb.
Erik Chandler left the band due to personal reasons after not performing for some time in 2019 and was replaced by long-time friend Rob Felicetti.
Frontman Jarret Reddick has spoken openly about his battle with anxiety and severe depression.
“The doctor and my therapist both agreed on the diagnosis, and it was like a lightning crash – they would describe the symptoms of depression, and I literally had all of them,” he told Kerrang! magazine.
“That was hard for someone like me to take: to be ‘the funny guy’, to be the guy in Bowling For Soup that tells the fart jokes, to be the guy that walks into the room and no matter what can turn it on and make everyone laugh… to be told that I had depression was like a punch to the stomach.”
In 2018, a fan-created High School Never Ends musical was made and was even performed at the Waterloo East Theatre in London in 2019.
Further performances were planned for April this year but were put on hold due to the coronavirus pandemic.
Canadian rockers Sum 41 burst onto the scene with Half Hour Of Power and All Killer No Filler at the start of the noughties.
Best known for singles Fat Lip and In Too Deep, the band became the kings of the summer college party anthem.
Dave Baksh announced he was leaving in May 2006 due to “creative differences” and headed to new band Brown Brigade – while being replaced by Tom Thacker.
Drummer Steve Jocz then left in April 2013, leaving Deryck Whibley as the only original member.
There was a hiatus in 2014 when Whibley battled his demons, bravely explaining that he nearly died five times from alcohol abuse after his liver and kidneys collapsed.
He explained: “I remember a doctor coming in and saying, ‘I’m going to be honest – we don’t know if we can save you. You could die. We’re going to do our best, but we can’t promise you’re going to live.
“Things were failing while they were trying to fix me. I almost died five times. They’d take me to intensive care and bring me back to life again.”
Whibley spent months in hospital and was unable to stand on his feet for more than three seconds at a time for the first year.
Jocz was replaced by Frank Zummo and Baksh made a return to the band in August 2015.
They went on a world tour in 2016 and announced released a new album in 2019.
Good Charlotte became a major success in 2002 with their hit singles The Anthem, Lifestyles Of The Rich And Famous and Girls & Boys.
Then they went slightly darker with their next album but returned to their punk roots in 2010 before going on a four-year hiatus from 2011.
The Madden brothers decided to go it alone and continued making music until the band got back together in 2015.
The identical twins also have very famous partners, as Benji is married to Hollywood actress Cameron Diaz.
The couple welcomed their first child by surrogate in December last year.
Not to be outdone, Joel Madden is married to American actress and The Simple Life star Nicole Richie.
