If you grew up in the ‘90s and ‘00s, or, heck, if you’ve even heard of the ‘90s and ‘00s, chances are you could sing entire Backstreet Boys and NSYNC albums, word perfect, from start to finish - and you’ve probably got a strong opinion on which plastic pants-clad, frosted tipped group is the supreme boy band. But what about all the other boy bands who wooed us with a hit or two before fading from view as quickly as they came?

We pledged our undying love to them, doodling our first names with their last names on our spiral-bound notebooks, only to forget them a couple years later. Backstreet Boys and NSYNC might dominate our collective memory, but that doesn’t mean that the other once-famous boy bands don’t deserve some love too. Today, we’re honoring the bowl cuts and 5-part harmonies that history forgot.

10 Westlife

If you blinked even once in 1999, you might have missed Westlife’s stint at the top of the charts. The Irish quintet enjoyed bigger success in the UK, but you know them from the one single they released in the US: “Swear It Again.” The lyrics, an impassioned declaration of their eternal devotion, combine with the honey-sweet melody to make this a boy band classic. Pull it up on Spotify and prepare for a blast from the past.

9 Dream Street

This group of 12-year-olds did what they came here to do (make one infuriatingly catchy pre-teen anthem) and then dipped. If nothing else, you gotta respect the efficiency. If you think you don’t know “It Happens Every Time,” check again - you probably do. This song may have buried itself deep in the recesses of your mind, but its chemically addictive properties ensure it will never truly leave you. Dream Street did spawn one celeb with a little more longevity, though: Jesse McCartney was the frontman for the group before leaving to pursue a solo career.

8 2gether

To be fair, you may not remember 2gether because they didn’t actually exist. 2gether was the titular boy band in an MTV series that parodied popular ‘90s boy bands like the Backstreet Boys and New Kids on the Block. Even as a fictional band, a couple 2gether singles actually made it into pop culture awareness; fire up “U + Me = Us (Calculus)” or “The Hardest Part of Breaking Up (Is Getting Back Your Stuff)” and let the memories come flooding back.

7 5ive

All 5ive wanted to do was make us dance. From “Keep On Movin’” to “Everybody Get Up,” from “Let’s Dance,” to “If Ya Gettin’ Down,” 5ive songs were mostly poppy, high-octane directives to party. And they worked! Seriously, we challenge you to listen to their biggest singles, “Slam Dunk (Da Funk)” and “When the Lights Go Out,” and NOT dance.

6 BBMak

BBMak exploded onto the charts with their debut single “Back Here” in 1999. You seriously couldn’t go anywhere without hearing this song. The trio didn’t exactly have the hunky boy band sex appeal that other groups had, but hey, they were cute and sweet and the song was good. They made it onto the charts a couple more times with singles like “The Ghost of You and Me,” though never to the same fanfare as “Back Here.”

5 No Authority

Only the real ones remember the LA-based quintet No Authority. The group started performing together in 1995 and Michael Jackson later signed them to his record label, MJJ Records. With such a mega famous cosigner, it’s a mystery how they faded to obscurity so quickly. They left us with one hit to remember them by: the delightfully frivolous “Can I Get Your Number (A Girl Like You).”

4 O-Town

O-Town was a boy band experiment, the first of its kind. The group formed on the MTV series Making the Band in 2000, another of producer and con artist Lou Pearlman’s boy band creations. By 2003, O-Town had disbanded, but not before leaving us with the hit single “All or Nothing,” and the cheekily libidinous “Liquid Dreams,” which chronicles a yearning for a fantasy amalgam of various female celebrities.

3 Boyzone

If you’re in the UK, Boyzone probably isn’t such a deep cut, but we Americans never really got the chance to get to know them. The Irish boy band enjoyed huge success in the UK from 1993 to 2000, churning out hits like “No Matter What” and “Picture of You,” even a cover of Tracy Chapman’s “Baby, Can I Hold You.” While they’ve taken hiatuses for several years at a time, Boyzone is still active today.

2 LFO

“Summer Girls” has probably stayed with you, but don’t sleep on LFO’s lesser known hits “Every Other Time” and “Girl on TV,” a music video that featured Jennifer Love Hewitt, whom lead singer Rich Cronin had briefly dated. Two of LFO’s three members, Cronin and Devin Lima, have tragically died since the group’s heyday, though third member Brad Fischetti keeps their memory alive with tribute performances and events to this day.

1 All-4-One

All-4-One may not have been around for very long, but they left us with a gem of a karaoke song, a must-have singalong for any road trip playlist: "I Swear." The lyrics of the 1994 hit were exactly the cheesy, passionate vows of eternal faithfulness that had us all so boy crazy back then. You might not have thought about this jam in years, but somewhere deep in your brain, the lyrics still exist - we swear.
