The Grammy Award for Best Pop Vocal Album is an honor presented at the Grammy Awards, a ceremony that was established in 1958 and originally called the Gramophone Awards, to recording artists for quality vocal pop music albums. Awards in several categories are distributed annually by the National Academy of Recording Arts and Sciences of the United States to "honor artistic achievement, technical proficiency and overall excellence in the recording industry, without regard to album sales or chart position."The honor was first presented in 1968 at the 10th Grammy Awards as Best Contemporary Album to The Beatles for Sgt. Pepper's Lonely Hearts Club Band. The category was then discontinued until 1995 where it emerged with the new name Best Pop Album. In 2001, the category became known as Best Pop Vocal Album. According to the category description guide for the 52nd Grammy Awards, the award is presented to artists that perform "albums containing at least 51% playing time of newly recorded pop vocal tracks."The award goes to the artist, producer and engineer/mixer, provided they worked on more than 50% of playing time on the album. A producer or engineer/mixer who worked on less than 50% of playing time, as well as the mastering engineer, do not win an award, but can apply for a Winners Certificate.Adele and Kelly Clarkson are the only two-time winners of this award, and Clarkson was the first to win twice. Clarkson leads all performers with six nominations. Source: Wikipedia (en)
