Michele had already completed her first solo album at the time which she has said that Monteith had often made notes on to help Michele. She then decided to postpone the album's release date, which was supposed to be very shortly after Monteith's death, and instead included songs that were tribute to Monteith's death - 'Cannonball' and 'If You Say So'.
Michele has spoke about the songs few times but in one of her videos for her YouTube channel where she described each track on the album, she said this about 'If You Say So':
"What it's about is sort of personal to me. I think that there will be a time where I'm happy to be talking in detail about it but for now I think, why I wrote it with her (Sia) was because when you lose someone, you know, one of the scariest parts of the process is being so afraid that you're going to forget. I'm 27 and I hopefully have many years ahead of me in my life and to think that I would have had a time in my life with someone and what if over time I forget things? So, I sat down with her to write this song about my relationship and we ended up writing about the last conversation I had with my boyfriend and how thankful I am to have had our last words be 'I love you'. So, it really is sort of self-explanatory when you listen to it, it's very personal to me, but this album is personal and it wouldn't be 'me' if I didn't let people in like that."
