Brick is a top ten U2 song for me. Gloria, Rejoice, Tomorrow, October, With A Shout, and Stranger In A Strange Land are all among my top thirty or forty U2 songs, too. I enjoy all the others songs as well, and I think Is That All is a perfect closer for an album.
It sounds a lot more powerful than Boy, and it's more raw and atmospheric than War. Maybe the lyrics are worse, but if I wanted good lyrics I'd read a book.
