"Get on Your Boots" sounds like a demo of four different songs stuck together with a cliche U2 bridge. It pains me to say this to you, because I simply adore you. Perhaps it's ok for a fanatic to question those s/he follows...? I guess you are allowed a throw-away song, especially since you've given so many crystalline and enduring notes, but not for the first single in nearly 5 years. I would have accepted a slightly engineered "Mercy" with grace. Your single is a B-side oddity, a bubble gum wrapper.
You are U2. I want you to sing about wars among nations with your heart on your sleeve and notes so pure they scratch the sky. I don't want to roll around the ditch with the miscreants. I don't want dirty. I want soundscapes and endless horizons and hope. Well...I am a patient and loving believer. I will await the rest with faith.
