The title track of Ledisi's eighth studio album, this was inspired by the King of Reggae. She told ABC Radio: "When 'Let Love Rule' came about I was thinking, 'I just love Bob Marley. I'm about to go to Jamaica. I've been studying him for a year and a half now on top of learning all this music. I want that feeling.'"
Ledisi added: "I was like, 'I want this vibe. This energy. I'm tired and I really don't want to be here, but I'm here.'"
This was the first song that Ledisi recorded for Let Love Rule. It was originally cut from the list of songs to include on the record, but was eventually returned to the tracklist. Ledisi explained:
"I said [to my producer], 'Can we just call the album Let Love Rule? since it's the first song I ever wrote for this project?' The first song I cut, the first song I write, the first song I let go of and the first song I bring back."
"Piano Man" was inspired by Billy Joel's time playing at a piano bar in Los Angeles. The "real estate novelist" was a guy who always talked about writing a book, but spent all his spare time in the bar.
