Jagged Little Pill is the third studio album and the first to be released internationally by Canadian singer-songwriter Alanis Morissette. The album saw Morissette changing her style and genre. Morissette's sound in the album was rock, but her previous songs were dance pop. The title is a metaphor for lessons of life that are hard to accept. The album was Morissette's breakthrough album, and contained six hits, "You Oughta Know", "Ironic", "You Learn", "Hand in My Pocket", "Head over Feet", and "All I Really Want". The album spent twelve weeks at number one on the U.S. "Billboard" 200 albums chart. By 2009, the album had sold 33 million units worldwide. It was ranked by the "Billboard" 200 as the number one selling album of the 1990s.
