LOS ANGELES (AP) — The smash hit “Bad Day” should have been a good thing for Daniel Powter: The upbeat tune put Powter on the musical map.

It not only became the biggest hit of his career, but it was also the No. 1 song of 2006. With assists from countless spins on the radio and use as the farewell song on “American Idol,” it went on to sell more than three million copies in the United States alone.
