Fans of a popular 2000s rock band are panicking after the countdown to a big announcement ended with a mysterious message.

Linkin Park started a 100-hour countdown on its official website and social media accounts on Saturday, leading to speculation about a new tour with a new lead singer. The countdown ended Wednesday afternoon, seemed to falter, and then started counting down again.

“It’s only a matter of time…” Linkin Park’s official social media accounts announced as the countdown began to run backwards.

Fans reacted with a mixture of frustration, confusion and jokes.

“What does this mean?!” one fan wrote on X, sharing a clip of the clock starting to count down.

“MAN WHAT IS GOING ON,” wrote one Instagram user.

“Every time you guess the new Linkin Park singer wrong, 100 hours are added to the timer,” one tweet read.

“In the end, the Linkin Park countdown didn’t even matter,” wrote another X user.

“I can’t believe I got trolled by one of my favorite bands,” one commenter wrote on Instagram.

“Shinoda, count your days,” wrote another.

As of Thursday morning, Linkin Park had yet to make any official announcements. Early speculation suggested the band would embark on a reunion tour with a new vocalist to replace original frontman Chester Bennington, who passed away in 2017.

Some theories suggested that Sum 41 singer Deryck Whibley would join LP after the pop-punk band’s “Fat Lip” farewell tour. Whibley said he made his own announcement on the same day Linkin Park’s countdown ended, but later clarified that he would not be rejoining Linkin Park, or Oasis, “or any other band.”

According to Arizona radio station 98 KUPD, Whibley’s announcement turned out to be an offer of a free, signed book cover to any fan who pre-orders his upcoming memoir, “Walking Disaster,” and presents proof of purchase at Sum 41’s merchandise table when their farewell tour resumes next week.

“Oh, how hard it is these days to plan an announcement without getting in the way of multiple other rock artists making their announcements at the same time and messing it all up,” Whibley joked.

Billboard reported earlier this year that Linkin Park members Mike Shinoda, Brad Delson and Dave Farrell were considering reuniting for concerts with a female vocalist in 2025. The group was one of the biggest acts of the 2000s with its blend of hip-hop, alternative rock and nu metal.

Orgy frontman Jay Gordon, who collaborated with Linkin Park on a remix of “Points of Authority” for the band’s 2002 album “Reanimation,” caused a stir in March when he told California radio station KCAL 96.7 that he had heard a Linkin Park reunion tour would feature a “female singer.” He later claimed he “didn’t know anything about” a new “Linkin Park female singer thing.”

Possible names that have been mentioned include Evanescence singer Amy Lee, a fan favorite from the same era as Linkin Park. She told iHeartRadio Canada in April that she had not been approached about the potential collaboration, but called it a “great” idea.

“They should ask me about that. I don’t have a lot of free time, but I could do it part-time,” she said.

Linkin Park, known for hits like “In the End,” “Numb,” “What I’ve Done,” “One Step Closer” and the Grammy-winning “Crawling,” fueled reunion rumors earlier this year with a new greatest hits release featuring a previously unreleased track, “Friendly Fire.” Shinoda, also known for his work as a solo artist and with Fort Minor, said that news would come from the band’s website.

“Rumors are always going around. People always ask what the band is going to do, and the best answer I can ever give is, if there’s anything to tell, we’ll tell you. If there’s an announcement to be made, it’ll be on LinkinPark.com,” he told Revolver magazine in April. “If you hear it from someone else, you can trust that information as much as you want.”
