In Decembe 2013, Pierre and Chuck did an interview with AMH Network and described the musical style of the next album:
Chuck: We have a lot of fans who are like: “I love the new song and the new record, but I love your first album style or the whole second record vibe, so I want you guys to do more rock.” And some fans are like: “I love your more pop songs!” So it’s a very interesting line for us cause we love doing fast, in-your-face kind of songs and we love doing the more pop songs and more like emotional songs as well. So, every record’s like a balance between those two-three things that we really love doing.
Pierre: I think for us it’s always a balance cause we love to do pop songs. I love to listen to stuff that’s like… Taylor Swift or stuff like that. Love that! I mean, it’s not what I am, but I enjoy it, so it’s cool to be able to kind of do some of the pop stuff but always have that punk-rock energy. But I think that definitely for the next album, we might go even more back to our pop-punk roots.
In late May 2014, Pierre and Chuck did an interview with ET Canada. They mentioned the sound of their new album as being very "throwback" - as Pierre said:
We have a good half-record now that we’re pretty stoked about I think. If I could say anything, it’s kind of a throwback – but even though the last record people called a throwback, I’m talking about throw-WAY-back!
According to ET Canada, the new music should have a "throwback '70s feel."
On June 20, 2014, Pierre and Chuck did another interview, this time with Amnesia Rockfest. The main focus of the interview was about the short reformation of their original band Reset, but they also spoke a bit about the Simple Plan album progress. They mentioned that they have a "rather punk rock" song that should be on the album.
On June 23rd, Pierre was a guest on Patrick Langlois’ morning show, Ça Commence Bien. Pierre talked about the new Simple Plan record, and he mentioned that they were inspired by big bands of the '60s. He also said that there were dance songs, in addition to other songs of all kinds of styles.
Throughout 2015, Simple Plan released four new singles. The first, "Saturday," had a youthful pop punk style with childish gang chants. That song will not be on the album, but is out as a stand-alone single. In the summer, Simple Plan released a pop punk love song called "Boom," followed by a rather gospel-influenced pop song featuring big vocals and horns called "I Don't Wanna Be Sad."
On September 18, 2015 Chuck did a live video chat on Facebook. He confirmed that "Saturday" will not be on the new album, though the other two singles will be. He also said the next single they released would be the official lead single for their fifth studio album. The record has a wide range of styles on it, from old-school pop punk to the soulful sound of "I Don't Wanna Be Sad." There are 2-3 ballads that he's especially proud of as well.
The first official single is called "I Don't Wanna Go To Bed." It has a slick, groovy sound and is more funky than punk. It's a great song, and it paired with the previous two singles show that Simple Plan is indeed expanding their musical horizons this time around.
