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.

Daniel Powter's "Bad Day" was used as the kiss-off song for the 5th 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.

I don't agree at all with Billboard's new criteria for a one hit wonder. It used to be that a one hit wonder was any artist that hit the top 40 of the singles charts only once. This was the standard for as long as Casey Kasem hosted AT 40 and now a OHW is defined as any artist that makes the top 25 only once. This new rule is totally stupid because some artists who weren't considered OHW's before the change will fall into that category.
