I agree with that, to an extent. But from the interviews I've heard, a lot of this album was written the same way. It just seems like they worked with each other a bit more in putting the finishing touches on. For example, 42 and The After Party are songs Andy wrote years ago, and have been floating around for a while. Admittedly though, they have said in multiple interviews that this album was more workshopped than the previous.
Also, you mention Kevin "bringing the rockers," like Friendly Advice. Friendly Advice is one of Andy's songs. And I'm pretty sure it's Robert playing the lead guitar, if that is what you're actually referring to.
Not trying to be a dick, but there's just some things in this review that caught my attention.
1. right, some of those songs existed before, but this album has the primary song writers working together more, at least it sounds like they put more focus on work shopping and making a cohesive project this time around, whereas on the first album felt like it had songs where they just placed obvious Andy parts mashed with an obvious Kevin part.
2. That was an oversight on my part, I meant to mention Petite Mort as an example of Devine having a few more upbeat numbers on the album.
3. just because they make an one time inside joke doesn't mean people dont "get" the title. I don't know what you are trying to prove here, was I supposed to write the entire first paragraph as a metaphor for Bad Boys 2?
