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.
Barbara Walters “10 Most Fascinating People” special has become a bit predictable, but leave it to Kate Gosselin to spark some interest in this year's show.
