You Oughta Know

"You Oughta Know" is a song by Canadian singer-songwriter Alanis Morissette and the second track on her third studio album, Jagged Little Pill (1995). It was released in July 1995 by Maverick as the album's lead single. After releasing two studio albums, Morissette met producer Glen Ballard in Los Angeles, with whom she wrote songs including "You Oughta Know". Despite much speculation concerning whom the song is about, Morissette has never disclosed the person's identity and has never indicated an intention to do so.

"You Oughta Know" was praised by critics for its lyrics, music, and Morissette's vocals. The song was a commercial success, reaching the top ten in three countries and the top 40 in six other countries; Morissette also held the record for longest run by a woman atop the Billboard Alternative Airplay chart until 2013. "You Oughta Know" won the Grammy Awards for Best Rock Song and Best Female Rock Vocal Performance, and the Juno Award for Single of the Year. Nick Egan directed the song's music video, which stars drummer Taylor Hawkins.

"You Oughta Know" helped Morissette enter the mainstream, and is often ranked among the best songs of the 1990s and of all-time. The song has continued to inspire other artists, many of whom have covered it in live performances. It also appears on three of Morissette's compilation albums.
