Speaking of the song's origin in an interview with MTV, Bareilles said of her label, "They had encouraged me to keep writing, and I just wasn't having any luck. I started to get really insecure about it, and then I got really pissed off at myself for caring what anybody thought. I went to a rehearsal space one day. I sat down and wrote something for me. And 'Love Song' basically wrote itself. It's totally honest, and I'm very lucky the label liked it as well." Later in 2011, she explained: "It was actually written for my record label. I had been turning in new music. I was getting the red light. I couldn't go into the studio yet because they were waiting for something. But I wouldn't nobody said what they were waiting for. So I kept turning in new songs, thinking like, 'Is this what you want? Is this what you want?' And it was always a big thumbs down, and I ended up writing 'Love Song' out of frustration." In 2014, she stated it was "very tongue-in-cheek" and "nasty in a passive-aggressive way," confirming it was a response to the record label pressuring her to make safe, "radio friendly" songs.
Music video
Directed by Josh Forbes, the music video features a miniature Bareilles playing the piano inside a coin-operated jukebox that plays love songs. A steady stream of men and women enter the booth and insert coins to observing her through a pinhole as she plays the same song day after day. The lyrics express her growing frustration as she declares that she is "not gonna write you a love song today," whereupon Bareilles grabs the next coin that rolls inside, and uses it to jam the gears. The next morning, the owner of the booth enters; he notices that the jukebox has gone dark, and appears amazed when he discovers Bareilles inside the jukebox. He retrieves the jammed coin from the gears and hands it to Bareilles. The music video features the album version of the song. The video also features British actorAdam Campbell as the owner of the booth.
