Query: A great album, thanks

The early release of the lead-off single "Vertigo" created an expectation in my mind that this would be a hard-rocking album of sizzling guitars and powerful vocals. What comes after that rip-roaring song is a carefully crafted, mature U2 album that is prettier and more open than expected. I think "Vertigo" created such a strong impression that it took me 2-3 listens before I could appreciate this album for what it is. And it's great! Thanks, U2, for another album worth waiting for.
