Hmmm, how do I want to state this. I think, for me, anyway, this is not my least favorite album from them (One by One and Echos, Silence, Patience & Grace is the clear least favorite to me) nor this is my favorite (which is There is Nothing Left to Lose and Wasting Light). The songs aren't really bad. There are some pretty good songs like Run, Arrows, and I do like La Dee Da.
I think they are stuck with the typical formula where the lead singles are most likely the best song of the album (although I did mention that I did not like The Sky is a Neighborhood, but Run was really great) and the rest of the stuff are just ok stuff. Wasting Light really did break that mold where Foo Fighters actually deliver a tremendous front to back album and I don't think Concrete and Gold did that here. Maybe on repeat listens, it could be a much better enjoyable listen.
