I know we've been through this before, but it's still odd to have the "Innocence" album cover with the old guy on it and the "Experience" cover with two teenagers.
Something about irony, I guess. The 50 year-old looking back on his innocence, and this time around it's Bono's letters to his kids or whatever.
On a basic level it doesn't make a whole lot of sense to the casual listener. And it's also been pointed out before that several tracks on SOI aren't about innocence at all, but rather experience (EBW, The Troubles).
