Summer of Love is absolutely the standout, with Little Things. It was love at first listen, so sonically gorgeous. Those two have bubbled up to be among my all time favorites.
The wails of "No, no, no..." totally make Red Flag Day, even if I didn't think this song is cool because it could've been on Boy.
The entire thread from Summer of Love all the way through to Landlady is
I about cried when I heard Love is All, and I'm a puddle of mush the entire back third of Little Things (pure U2 magic as others have said).
Many of the reviews have been annoying. Written by people who have no clue about the history and the back story behind many of their songs that put lyrics in context.
I wish only one song had released early, or that I hadn't listened, because they are now the ones I tend to skip. I feel like it has cheapened those songs, most of which are quite good too.
Landlady seems to underwhelm people, but I love it.
Overall, some of the songs have blown me away, many have surprised me, few have disappointed me--but not by much, and don't even get me started on Bono's voice. Beyond beautiful. So happy for them and for us that the vast majority of fans seem to love this album.
