Another other note?
Consider this Slate opinion:
U2 has now been good longer than any other important band in history. The Rolling Stones have been around forever, but their creative period lasted only 15 years. The Beatles imploded after a decade. U2 -- the same lineup of Bono, the Edge, Adam Clayton, and Larry Mullen -- has been making acclaimed albums since 1980's Boy.
...which is tempered by:
U2 is perhaps the world's vaguest band. [...] This is the U2 paradox. Bono and Co. are constantly dedicating songs to specific causes, exhorting their fans to think and act in the world. Yet their music does exactly the opposite of what it intends.
Then, right at the bottom, the coup de grace, from a reader:
It's a shame that U2 and the Monkees never collaborated on "Bloody Pleasant Valley Sunday."
