Really, having a free download in the iTunes page would be actually simpler for me. I've read in the news, was curious, tried over iTunes, I can't download. Surfing, seeing "it's complicated," gave up. U2 weren't interesting enough for me to actually make an effort.
I actually got up to "show all purchases" and immediately hated that I have to actually do this as the things I bought and discovered it was not what was advertised were visible again, just reminding me of something I'd rather forget. I wish there were just a simple possibility to "permanently delete the information that I've purchased particular tracks."
Then the special "U2 removal tool" weren't necessary too.
