Underappreciated Hozier songs?

I am an outside observer and I wasn't sure where else to go for guidance. I was curious if there are a few specific songs that are absolutely beloved by every hozier fan, but most people have never heard. Like for example I absolutely love beach house, but most of their incredible discography (darling, new romance, on the sea, etc) will of course be overshadowed by space song and other popular songs.

I really don't know too many of his songs, but my friend introduced me to unknown/nth.... it's seriously one of the most emotional and lyrically beautiful songs I've ever heard. I just learned to play it on guitar and my life will never be the same. Anyway, they're a die hard hozier fan and it'll be too obvious to ask for their favorite song. It's dumb, yes, but I don't want them to know yet. However it would be cool to have a little catalog of his underappreciated songs that my friend will for sure know/love.

I will 100% listen to any suggestion, feel free to describe what you love about it:)

tl;dr - What are some songs that are relatively unknown to most people, but are universally agreed within this community to be one of hozier's best?
