Honestly, I can't. I can only guess that "Love is Dangerous," "This is Home" and "MH.4.18.11" weren't done together, as they either sound like bland Angels and Airwaves or +44 songs.
I mean Tom agrees the distance had a huge effect....
What was it like making a record together after so much time away from Blink?
“I think we weren’t unified as a band. If we were to start now we’d be much more unified. Mark was in his studio in LA, I was in San Diego, everyone was so busy. Out of recording for a year, we were only in the studio as all three of us together for a total of one or two weeks. We only wrote songs together for three days. The rest was emails. But we accomplished it and that’s the big thing. The first song I sent over was Up All Night. People say that sounds like Angels on a Blink record. Well, no – that’s just me.”
And I think we've learned to not take much of what Tom says at face value, he's feelings on things seem to change and shift quite often. Furthermore, my main point is that while Tom may (now) thing some songs are weaker that were not written together -- songs like "Up all Night" are some of my favorite on the album, and I can't make a valid argument (backed with evidence) that where they wrote the songs made any one song better or worse than another. If I look at the list of where each was written and recorded and mixed and mastered and who was there and whatever -- there's no correlation to my enjoyment of the song. No pattern emerges. Therefore, it's very difficult for me to try and pin any failings on any one item. Instead, like most albums, there are parts I like - parts I don't like - and songs that I feel are better or stronger than others. The strongest songs don't rely on production to begin with ("After Midnight") and are just great Blink-182 songs.
I feel all of the extra bullshit is getting tossed around my fans without ever giving it any real thought -- they want a scapegoat and it's either Tom or the sound engineer or whatever.
Tl;DR: Blanket statements like "the production sucks" or "this album sucks because they didn't write it all together" make no logical sense given the realities and evidence to the contrary.
