As others, I've been debating between Running To Stand Still and One Tree Hill (with great pain of my heart for discarting Mothers, Exit, IGC, Red Hill MT and TTYWires)... but I eventually voted for Running To Stand Still. Personal reasons over musical quality
It's hard to say since this album is a masterpiece of heaven, but my choice is In God's Country...Such a powerfull song, full of energy, great vocals and great guitar
I love all of those songs, but ultimatley it was between Running to Stand Still and One Tree Hill, went with One Tree just because of some of the solos Edge used to play during it.
