In the livestream following the release of the album, Kirstin commented about “Anchor”:'

One of them, one of my favorites, has been around since 2014. I’d like to say it’s always been an OG fave for me!

The song utilizes the anchor as a metaphor for a relationship where one of the parts is unwilling to settle down and have a serious bond with the narrator, who despite everything still stays loyal to them.
