According to Leigh Nash, "God Only Knows
" is the most perfect song ever written, and "What's Behind Me" pays homage to the Beach Boys' classic number. She explained to American Songwriter
: "I think the melody and the lyric together are completely perfect. They fit like a hand in a glove. It's immaculate. I don't know how else to describe it. The feeling I get when I listen to that song… every time, too. It stops me in my tracks and I have to listen in detail because it's so awesome."
"I was talking about that song with one of the guys I write with one morning and we ended up writing one of the songs on the album as a tip of the hat to that song. It's called 'What's Behind Me' and it's kind of a tribute to 'God Only Knows.'"
