A one-hit wonder is a person or act known mainly for only a single success. The term is most often used to describe music performers with only one hit single. Generally, the term also is more applied to musicians best known for only one song.
In the U.S., a "pure" one-hit wonder is an artist that manages only one song on the Billboard Hot 100, regardless of the song's peak position. However, most American music industry insiders consider a song in the top forty positions of the Billboard Hot 100 to be a hit. Thus, any performer who recorded only one song that reached the Top 40 is, technically, a one-hit wonder, regardless whether another song peaks in the "bottom 60."

I think you got the definition wrong, or it's me
Amy and Bublé are not one-hit wonders. One-hit wonders are more like artists that released one hit and failed to achieve the same success and faded.
