Question: Which Canadian singer began his recording career with a self-titled debut album released on May 19 1998, and won Rolling Stone's Best New Artist award that year?
Context: The MTV Video Music Award for Best New Artist have been given out since the first annual MTV Video Music Awards in 1984.  From then to 2006, the award was named Best New Artist in a Video.  In 2007 its name was changed to Best New Artist, as the category underwent a format change to award the artist's body of work for the full year rather than a specific video.  For the 2008 ceremony, though, while the award retained its 2007 name, it returned to the format of awarding a specific video rather than the artist's full body of work.  The category was later renamed Artist to Watch through 2013 to 2015 while still keeping the format of an award going to a certain video. The Grammy Award for Best New Artist has been awarded since 1959.  Years reflect the year in which the Grammy Awards were handed out, for records released in the previous year.  The award was not presented in 1967.  The official guidelines are as follows: "For a new artist who releases, during the Eligibility Year, the first recording which establishes the public identity of that artist."  Note that this is not necessarily the first album released by an artist. Amy Holland is singer Amy Holland's self-titled debut album.  The album was released on LP record in 1980, and was produced by Amy's future husband Michael McDonald.  One of the songs on the album "How Do I Survive" (a song originally sung by The Paul Bliss Band) became a big hit and made it to the Top 30 chart.  Amy Holland would often perform "How Do I Survive" live on music TV shows such as Music Fair (a Japanese music show) and Young Oh!  Oh! .  Those live performances of the song can be found on YouTube.  Holland mostly recorded some song covers for this album, with one of them being Annette Hanshaw's 1928 jazz-standard "Forgetting You" The success of the song "How Do I Survive" helped Amy earn a Grammy Nomination for Best New Artist in 1981, but she did not win the award however.  Some of the songs on the album have been written by Michael McDonald such as "Here In The Light" and "Show Me the Way Home".  "How Do I Survive" was a hit peaking at #22 on the "Billboard" Hot 100.  Three years later Amy would release another studio album called "On Your Every Word".
