I agree with others that it suggests it'll sound like the more 'radio friendly' tracks on SoI (I.e. The first half, with tedder and Epworth credits).
What I'm really curious about is how long they've been working with Tedder. I said this a while back, but if u2 really want to work with a commercial producer, I wish they'd do it from the start of album sessions rather than towards the end as a 'clean up' maneuver.
The way they've done it at the end of the last couple albums (sessions only with Lillywhite for NLOTH, sessions with tedder and epworth for SoI) has yielded to me very disjointed works.
It's very jarring having Song for Someone and California alongside Sleep like a baby Tonight and Raised by wolves. (The lyrical content does link them, but sonically they're way too distant to me).
Likewise, going from Unknown caller to too Crazy tonight is I'd just too much.
They've shown a tendency to bring in pop producers at the last minute, and we all know they're chasing a big single. It was almost inevitable in retrospect that they'd bring in Tedder for SoE; I just hope it's been from the beginning, rather than right at the end. It would be nice to have a more cohesive album - 'Innocence' almost sounds like two ep's taped together.
