Query: A masterpiece!

I do not understand why more people do not feel the way that I do about this album -- this album has given me songs to listen to that seem to get better with every playing, and that both lift you up, give you something to think about and tug at your heart. This album truly is a sort of homecoming for U2, and all I can say is thank you, thank you, thank you for a wonderful masterpiece.
