Powter has not had a big hit since Bad Day
Canadian singer-songwriter Daniel Powter has been named the decade's top one-hit wonder by Billboard magazine.
Powter's single Bad Day spent five weeks at the top of the US Billboard chart in 2006 and was also a big hit across Europe.
Billboard describes a one-hit wonder as an act whose second single did not reach the top 25.
It is based on acts from 2000 to 2007, as someone who released a single last year may just be taking a break.
Number two on the list is Terror Squad for Lean Back, third is Crazy Town with Butterfly, MIMS is at four with This Is Why I'm Hot and number five is D4L with Laffy Taffy.
Powter's Bad Day was the most played song in the UK between 2002 and 2008, the Performing Rights Society said.
"It's got one of those three or four-word lyrics that means something to everyone's everyday life," said Russell Hier of SonyBMG last year.
"No-one wants a bad day, but everybody has one."
