(CNN) -- Davy Jones was more than just the star of countless bedroom wall collages in the late 1960s.
The Monkees frontman and token Brit who captivated audiences with his talent and charisma was the quintessential teen heartthrob.
News of Jones' passing (he died of a heart attack at age 66 Wednesday) prompted nostalgic outbursts from fans, all wanting to reminisce about the Tiger Beat and 16 Magazine covers, the hours logged in front of the TV, and the moments spent bopping around to "Pleasant Valley Sunday."

Whether the grief stems from the feeling of closing a chapter in one's own life, or the larger question of mortality, the death of a former teen idol can have a profound effect on fans.
Like Michael Jackson, who died in 2009, and Whitney Houston, who died last month, Jones was someone younger generations looked up to as "the first person who made them interested in music," said Phil Gallo, Billboard's senior correspondent.
For many people, The Monkees were the first group they could claim as their own, as opposed to the music that belonged to their parents, Gallo added. "That really affects people," he said.
And then there was Jones' teen heartthrob status.
"If you talked to any girl who liked The Monkees, invariably, (Jones) was her favorite," Gallo said. "It's the lead singer. It's the cute one. The one who's got the nice personality."
But that fandom isn't limited to the girls who would've gladly traded a limb for a date with Jones.
"When I was a kid, I wanted to BE Davy Jones," actor Kevin Bacon tweeted. "Big part of what led me to showbiz."
A lot of the people who are grieving this loss are in their 40s and 50s, Gallo said, adding, "It's a case of, 'Wow, he's one of me.' People think of him as, 'He's from my lifetime. He's my age.' "
And though it seems like a far departure, that's how today's youths will view pop star Justin Bieber.
Sure, the magazines have changed -- now it's J-14 and Twist -- and Jones' fitted button-down shirts have been replaced by purple hoodies. But the significance of teen idols remains the same. (Ironically, so does the hair.)
In 2008, one year before Bieber earned his teen heartthrob status, Yahoo! Music named Jones the top teen idol of all time, ahead of Jackson and David Cassidy, who shared the honor with Bobby Sherman and Donny Osmond in the early 1970s.
Taking a page out of The Monkees' book, Bieber has taken advantage of this time in the limelight, releasing a memoir, a movie, appearing on "CSI: Crime Scene Investigation," and touring, all while making music.
Jones guest-starred as himself in a 1971 episode of "The Brady Bunch," appropriately titled "Getting Davy Jones." The now iconic episode, in which Jones performs "Girl" for Marcia at her prom, was beloved by fans.
"There's something about The Monkees and what that told us about pop culture and how music and TV and, eventually, film can work together," Gallo said. "This is sort of a lesson that people can still learn from, and it keeps getting repeated five decades later."
The Beatles -- the group that inspired The Monkees -- released "A Hard Day's Night" in 1964. Three decades later, '90s superstars, The Spice Girls, came out with the movie "Spice World."
"The teen idol marketplace is really a two- to five-year window," Gallo said, and that was understood back when The Monkees were at their peak.
But the thing that makes The Monkees different is that their music managed to transcend generations, Gallo said. "Oldies radio or commercials or ... on TV shows, (their music) kept getting used in the '70s and '80s, so when they had a comeback, there was an audience for it."
After first finding fame in the late '80s and mid '90s, New Kids On The Block and Backstreet Boys, respectively, experienced a comeback of sorts when they toured together.
As former fans become parents, and introduce their children to The Monkees, Gallo said, their audience will grow. Not to mention that Smash Mouth's version of "I'm a Believer" appeared in 2001's "Shrek."

"There will come a day that somebody is going to play The Spice Girls or *NSYNC for their kids and say, 'Let me tell you how great music used to be,' " Gallo said.
"It's kind of hard for us to fathom, but in the same ways someone says 'Pleasant Valley Sunday' is a great song and, 'They don't write (songs) that way anymore,' I'm sure somebody will say that about 'Backstreet's Back' one day."
