Taylor Swift may have only been 5 years old when Alanis Morissette released Jagged Little Pill, but 20 years and a few breakups later, she knows that that was some cathartic stuff.

Alanis is releasing a collector’s edition of Jagged Little Pill. Taylor Swift: friend to all women whose names do not rhyme with Hatey Larry.
