Rewinding The Charts: In 1995, We Got To 'Know' Alanis Morissette

'You Oughta Know' rose to No. 1 on Alternative Songs … even if she didn't remember recording her U.S. breakthrough

"When I was writing it, it was so subconscious. I wasn't aware of what was coming out of me," 21-year-old Alanis Morissette told Billboard shortly before "You Oughta Know," the scathing first single from her debut Maverick/Reprise album, "Jagged Little Pill," topped the Modern Rock Tracks chart – now Alternative Songs – the week of July 22, 1995.

"I'd go into the booth ... and sing. I'd listen the next day and not really remember it."

The results proved enduring. "Jagged Little Pill" has sold 14.9 million copies domestically, making it the third-best-selling album since Nielsen SoundScan began tracking sales in May 1991.

"You Oughta Know" signaled a makeover for the Canada native, now 40, whose earlier work had leaned pop/dance. It also sparked debate about the identity of "Mr. Duplicity." Comic actor Dave Coulier ("Full House"), who dated Morissette in 1992, had copped to the dubious distinction in interviews, but, in June, called the story an "urban legend."

Morissette, who wed and became a mother in 2010, remains mum on the subject.
