Need a song to play softly in the background during a proposal? Or just want to add to your Castle playlist? Read on for our music guide for “Nikki Heat.”

Artist: Amos Lee
Song: “Flower”
Album: Mission Bell

The album will be released on January 25. Pre-order on iTunes or Amazon.

You heard it when: Ryan did the cutest thing ever and proposed to his girlfriend Jenny at the station. He’ll always remember her blue dress and the stares of a dozen or so colleagues who surrounded the couple after she said, “Yes!”

This song worked because: Lee’s soulful, folksy voice goes a long way to set the romantic (but not overly cheesy) mood. The only line from the song you really hear is, I believe in the power of love, and given the occasion, that pretty much fits.

Lee’s upcoming fourth album Mission Bell will feature Big Time Music People like Willie Nelson and Lucinda Williams. His songs have also been featured on Brothers and Sisters, Grey’s Anatomy, and Parenthood.
