Kravitz on popmatters.com about this piano ballad: "The song is pretty simple. It's strong and emotional. My records are very diverse. If you hear one song, you've got no idea what the next one is going to be like."
"I'll Be Waiting" is the theme song for the Japanese Death Note spin off film L: Change the WorLd. Kravitz said, "When I heard that my new single will be used as the theme of a worldwide hit movie, I was very excited. I'm glad to be able to have this wonderful opportunity, and I'm thrilled to play it before everyone."
In a 2018 interview with The Guardian, Kravitz said of the unrequited love song: "There's always somebody waiting for somebody else to get their shit together."
For It Is Time For A Love Revolution, Kravitz set up a recording studio in the ballroom of the Edison hotel in New York City's Times Square. The black-and-white music video, directed by Kravitz and Philip Andelman, shows the singer laying down the track, including piano, bass, guitar, and drums. He's wearing a T-shirt with the phrase "Music Saved My Life."
