The Pretty Reckless is a great band, in part because Taylor Momsen has such a great voice. So let's listen to that voice.
I wrote that song when I was 25, [and] we recorded it right after I turned 25. It's very autobiographical, in a lot of ways. I thought it would be an interesting idea to figure out a way to go through all the years of my life and somehow calculate that and have it end with 25. But the inspiration was really drawn from me just reflecting on my life up until that point, writing this autobiographical song from a place of despair.

This song is "25 [Unplugged]" by Taylor Momsen of The Pretty Reckless with Duncan Watt on piano.
