I love both of these songs!
"
Ironic" was a song by Alanis Morissette, found on her debut album
Jagged Little Pill, and released in 1995.
"
My Favorite Mistake" was a song by Sheryl Crow, found on her 3rd album
The Globe Sessions, and released in 1996.
Both of these songs have a lot of irony in them. And they also have nearly the same beat! I mean, how can someone have a favorite mistake? And who wants rain on their wedding day?
Someone having a favorite mistake or rain on their wedding day are both ironic.
