RIP Brad Arnold.🕊️ It’s hard to explain to people who weren't there just how massive 3 Doors Down was in 2000. He wrote "Kryptonite" in a math class when he was 15 years old. Five years later, it was the biggest song in the world. 47 is way too young. I was lucky enough to see him in Phoenix in Sept 2024 at the Summer of '99 tour with Creed. He stopped the show to talk about how many of us feel like we'll never be good enough, and then reminded us we're absolutely enough because Jesus loves us. "You are absolutely enough. You will always be enough... because Jesus Christ loves you." Rest easy, Brad.😢

The Hangover is still ridiculously funny. Wild that a 35-page script outline somehow turned into one of the sharpest comedies of the 2000s. It still kills every rewatch.

3 Doors Down lead singer Brad Arnold has sadly passed away at the age of 47 after a battle with kidney cancer. "With his beloved wife Jennifer and his family by his side, [Brad] passed away peacefully, surrounded by loved ones, in his sleep after his courageous battle with cancer," 3 Doors Down said in a statement. "Brad's songwriting became a cultural touchstone for a generation, producing some of the most enduring hits of the 2000s, including the band's breakout hit, "Kryptonite," which he wrote in his math class when he was just 15 years old." "His music reverberated far beyond the stage, creating moments of connection, joy, faith, and shared experiences that will live on long after the stages he performed on." "Above all, he was a devoted husband to Jennifer, and his kindness, humor, and generosity touched everyone fortunate enough to know him. Those closest to him will remember not only his talent, but his warmth, humility, faith, and deep love for his family and friends." Back in May, Arnold released a video, revealing that he found out he had cancer. Rest in peace, Brad.

nothing special. Namjoon was just 22 when he saw leaves falling from the trees and wrote Spring Day, which went on to become one of the biggest hits of BTS's career.

Tomorrowland (2015) had one of the best sci-fi concepts of the decade and somehow turned it into a lecture. Brad Bird built a world that promised wonder and discovery, then buried it under speeches and plot noise.

Brad Arnold from 3 Doors Down really fought until the end. The man who gave us the soundtrack to our worst heartbreaks just lost his battle with cancer today, February 7, 2026, at the age of 47. From writing "Kryptonite" in math class to helping us survive those lonely nights with "Here Without You," his voice was there for every heavy moment. How many of us played those records on repeat just to feel something when the world got quiet? Rest easy, legend. You weren't just a singer; you were the friend we needed when life got real.

Throwback to 2000: A time when trance transported us beyond reality. One of the most hauntingly beautiful anthems of the millennium. With its dark, driving bassline, hypnotic melody, and emotional atmosphere, Strange World captured the essence of 2000s trance like few others.

"Teenage Dirtbag" is 100% autobiographical. Brendan B. Brown (vocals) wrote the song based on his own adolescence on Long Island. Released in 2000 as the first single from Wheatus, it became one of the greatest anthems of the 2000s and exploded even more after entering the soundtrack of the film Loser.
