I don't even count Saints. But if I had to, it's a failed experiment. I'd actually rather hear Billie Joe's voice than Bono's on that one. When Bono's voice enters the mix, it is too bombastic and destroys any subtely or build-up the song had going for it. The best thing about the song is the double drum attack. So I'd say 3/10.
Windows on the other hand, is decent. Not my favorite song by any means, and the chorus is really really REALLY annoying (this is a song u have to listen to once in a blue moon. If you keep this one on repeat u are gluttin for punishment). However, I like the arrangement (sans Edge's uninspired, phoned-in performance), and the band can play it well. The middle parts of the song are pure melodic heaven, and the verses aint bad either. Why in God's name did they butcher the chorus? If they went about the chorus in a different way, it could've been a great song. But for now, it's average. So I'd give it a 5. And for U2 these days, a 5 is actually pretty good.
Did someone say Vertigo has bite? I'd say it has a lot of bark. Not much bite. And it has also been neutered. And it's a chiwawa. A very noisy one. But no threat by any means.
I'm not suggesting that Windows has bite. It aims to be a cheesy pop song, and in the end that's what it is.
