They came, they conquered ... they were never heard from again. After reaching the Hot 100's Top 10 with their very first singles, none of these acts managed to crack the Top 25 for the rest of the decade. But hey, four minutes of fame is better than nothing.

The one-hitmakers on this list have been ranked by how high their big song climbed on the chart compared to how far down the tally their subsequent highest-charting effort peaked.

1. DANIEL POWTER

BAD DAY

Daniel Powter's Bad Day was used as the kiss-off song for the fifth season of American Idol, which gave the song enough juice to become the biggest single of 2006. The song went to No. 1 in April and stayed at the top for five weeks. But Powter's good fortune didn't last long; he hasn't visited the Hot 100 since.

2. TERROR SQUAD

LEAN BACK

Terror Squad, the hip-hop collective led by Fat Joe, topped the charts in August 2004 with Lean Back, giving the world a new dance craze in the process. The Squad fell back hard after that, only reaching as high as No. 62 with a subsequent single: Take Me Home, at the end of 2004.

3. CRAZY TOWN

BUTTERFLY

L.A. rap-rockers Crazy Town flew to the top of the charts with the Red Hot Chili Peppers-infused track Butterfly in March 2001, and hovered at No. 1 for two weeks. The band's wings were clipped after reaching that peak; they never saw the Hot 100 again.

4. MIMS

THIS IS WHY I'M HOT

MIMS told the world This Is Why I'm Hot, and sizzled at the No. 1 spot for two weeks in March 2007. The Jamaican rapper's next single, July 2007's Like This, only went as high as No. 32. Not quite as hot.

5. D4L

LAFFY TAFFY

Atlanta's D4L hit a sweet spot with Laffy Taffy in January 2006, when the song peaked at No. 1. The foursome only made it to no. 72 with their next single, Betcha Can't Do It Like Me.

6. JAMES BLUNT

YOU'RE BEAUTIFUL

James Blunt sweet-talked his way to No. 1 with the inescapable ballad You're Beautiful in March 2006. But fans dropped him soon after; his appropriately titled next single, Goodbye My Lover, only reached No. 66.

7. GNARLS BARKLEY

CRAZY

Crazy was such a gargantuan smash, it felt like Gnarls Barkley's spell would never wear off. But after peaking at No. 2 in July 2006, Ceee-Lo and Dangermouse haven't made it past No. 88 with their subsequent singles. Crazy, indeed.

8. BLU CANTRELL

HIT 'EM UP STYLE (OOPS!)

Blu Cantrell struck gold with Hit 'Em Up Style (Oops!), which reached the No. 2 position in July 2001. Since then, she's climbed only as high as No. 70, with Breathe in 2003. Oops!

9. BO BICE

INSIDE YOUR HEAVEN

Bo Bice won the hearts of American Idol viewers with Inside Your Heaven, which peaked at No. 2 in July 2005. After the cameras turned off, voters quickly tuned out. His next highest-charting single, The Real Thing, peaked at No. 56 in May 2006.

10. DREAM

HE LOVES U NOT

Dream lived up to their name with He Loves U Not, which climbed to No. 2 in December 2000. After that, the manufactured girl group woke up and rose only to No. 39 with their next single, This Is Me, in the summer of 2001.

11. J-KWON

TIPSY

J-Kwon intoxicated the airwaves with Tipsy, scoring him the No. 2 spot in April 2004. He hasn't stumbled as high on his own since, but he did ride Bow Wow's coattails to No. 23 in April 2006 with the collaboration Fresh Azimiz.

12. CASSIE

ME & U

Cassie strutted to No. 3 with Me & U in July 2006, but she floundered with Long Way 2 Go, which only peaked at No. 97. She's been a no-show on the charts ever since.

13. Lou Bega

MAMBO NO. 5 (A LITTLE BIT OF...)

Lou Bega's ubiquitous Mambo No. 5 (A Little Bit Of) climbed to No. 3 in November 1999, and stuck around for months after peaking. But Bega hasn't flirted with the charts much since; his next-highest charting single, Tricky, Tricky, only reached no. 74 in February 2000.

14. LIL' ROMEO

MY BABY

Cute and cuddly Lil Romeo skipped all the way to No. 3 in June 2001 with My Baby. But puberty didn't do the pint-sized rapper well; none of his solo singles have even touched the Hot 100 since.

15. LUMIDEE

NEVER LEAVE YOU - UH OOH, UH OOOH!

Lumidee promised to Never Leave You with her first single in August 2003, which climbed to No. 3 on the charts. She didn't keep her word. Outside of a No. 43 appearance in April 2007 with She's Like the Wind featuring Tony Sunshine, she hasn't visited the Hot 100 since.

16. HINDER

LIPS OF AN ANGEL

With Lips of an Angel, Hinder soared to the No. 3 spot in October 2006. The band fell from grace shortly thereafter, soaring only as high as No. 31 with Better Than Me in May 2007.

17. KEVIN LYTTLE FEATURING SPRAGGA BENZ

TURN ME ON

In August 2004, Kevin Lyttle, with help from Spragga Benz, lit up the charts with Turn Me On, which peaked at No. 4. The airwaves have since turned him off, and the Caribbean crooner has yet to return to the Hot 100.

18. YOUNGBLOODZ FEATURING LIL JON

DAMN!

Youngbloodz teamed up with Lil Jon on Damn!, which rose to No. 4 in November 2003. The Hotlanta duo had much to curse about after that; they didn't go nearly as high with their next biggest hit; Presidential peaked at No. 81 in November 2005.

19. FORT MINOR FEATURING HOLLY BROOK

WHERE'D YOU GO

It's a good thing Mike Shinoda has Linkin Park to fall back on. Fort Minor, his musical side project, started big, reaching No. 2 with Where'd You Go in June 2006. Fans have been asking the same question since then; the band's next biggest hit, Remember the Name, peaked at No. 66. three months later.

20. SAMANTHA MUMBA

GOTTA TELL YOU

Irish singer Samantha Mumba rose to No. 4 on the Hot 100 with Gotta Tell You in December 2000. The airwaves refused to listen after that; her next-biggest single, Baby, Come Over (This Is Our Night) climbed only to No. 49 in June 2001.

21. CASSIDY FEATURING R. KELLY

HOTEL

Cassidy went all the way to No. 4 in March 2004 with Hotel, featuring R. Kelly. But the Philly rapper checked out of the chart shortly thereafter, only making it as high as No. 33 with My Drink N' My 2 Step three years later.

22. MACY GRAY

I TRY

Macy Gray blew up in May 2000 when her debut single, I Try, went to No. 5. But believe it or not, the husky-voiced diva has not appeared on the Hot 100 since.

23. THE CALLING

WHEREVER YOU WILL GO

In March 2002, L.A. rockers the Calling reached their highest high when their single Wherever You Will Go peaked at No. 5. The band has not come calling back to the charts since.

24. VANESSA CARLTON

A THOUSAND MILES

Vanessa Carlton wooed listeners in May 2002, when her piano ballad A Thousand Miles hit No. 5. Five months later, she was back on the Hot 100 with Ordinary Day, but the song -- her second-biggest single -- barely cracked the Top 30.

25. RUFF ENDZ

NO MORE

Baltimore R&B duo Ruff Endz went all the way to No. 5 with No More in September 2000. But the group never saw the top 10 again after that; they only reached No. 49 with Someone to Love You in June 2002.
