"Love Song" was initially written as a response to her music label's request for a commercial hit. The label wanted Bareilles to write something "radio-friendly" which she didn't like. She wrote "Love Song" as a rebellion against the label, and it ended up being her first top 10 hit on the Billboard Hot 100 chart. #BehindtheMusic
I don't like it very much before the day is over, I feel it lacks energy and the singer's voice is quite boring, it's not my vibe, but maybe someone else likes it better.
