It's unbelievable how people complain about free music from a great band.

Well, a step closer to that lofty goal would have been to give everyone a code to redeem and let them choose whether to redeem it or not. Yes, you would then have people unhappy about not being able to redeem the code for a different album from a band they like better than U2, but at least you haven't gone and monkeyed with people's accounts without their permission.
