It is 20 years since Alanis Morissette released Jagged Little Pill, the album that rocketed her to fame. But the Canadian singer still remembers it like it was yesterday. Back in 1995, her third studio album was expected to sell only modestly, until a Los Angeles rock radio station started playing the angst-ridden first single, You Oughta Know. The next day "there was a lineup around the block and there were people singing You Oughta Know way louder than I was and I just thought: 'Oh. This is no longer mine'," Morissette said.Jagged Little Pill sold 33million copies and earned her four Grammy awards. The 20th anniversary collector's edition, to be released today, includes 10 previously unreleased demo tracks, a concert video from her live British debut, and an essay by the singer.Morissette, now 41, married and with a young son, said having millions of people listening to her innermost thoughts was not as scary as she had thought it would be: "Every record that I put out, every song and every single, I'd wake up at four in the morning the night before it was released. I'd be gripped with terror. And I realised the more transparent I was, the more empowered I felt."..
