Alanis Morissette and Glen Ballard wrote Thank U after returning from a trip to India in 1997. The song expresses the heartfelt gratitude which she felt at the time. The lyrics, such as “thank you terror” and “thank you frailty”, lend the song a sense of lyrical reflection on cynicism, despair, personal triumph and hope. Thank U is Morissette’s most commercially successful post-Jagged Little Pill single. The music video was directed by Stéphane Sednaoui.
