Niceman, part of the reason this has kind of gotten circular is because you've kinda changed the terms of the debate.
Now you say this...
You're arguing against something I've never stated.
I said, "U2 is apparently producing lots of material which is not getting released."
But originally, you said this...
I don't buy for a second that U2 is less productive now than they were 10, or maybe even 20 years ago. They just don't share.
People merely pointed out to you that any statement about how much completed, unreleased material U2 has is speculative. Indeed, you're merely guessing that they have enough material to make them as productive as they previously were just based on vague comments by Bono. That's the very definition of speculation.
And this...
Yes, you are arguing that the only way the word "productive" can be used is "releasing albums," even though I have made it crystal clear that I wasn't using it that way.
...is s a straw man. Yes, we can agree that an unreleased song is still productivity, but since we don't conclusively know how many of those there really are, how can we conclude there's enough to make them productive as ever?
The issue isn't defining productivity...by whatever definition you use, there still has to be a way to
measure that productivity, if you're going to make an informed observation on it. Otherwise, yeah, you're just guessing. The only way we have to accurately measure productivity is by looking at what they've actually released.
And the "I don't think Bono is lying" thing is a straw man also. No one said Bono is lying. But I haven't heard any comment by him to conclude that they have the amount of completed, unreleased work to credibly say that they are as productive now as ever. Again, you're just guessing. Now, it's possible you're guessing correctly, but we really don't know. Again, I'll give you that an unreleased song is still song, but without any tangible evidence of how many of these there are, we can't draw any valid, provable conclusions, can we? I mean, under your criteria, to really gauge how productive they in one decade vs. another, not only would we have to speculate about unreleased songs in the 00's, we'd have to go back to what they said about unreleased songs in the 80's and 90's and guess how many of those there were as well. Because surely there are some. See why this line of reasoning doesn't work?
The ONLY way to objectively compare how productive they are, without engaging in guesswork, is to compare apples to apples based on
known data...how much they released now vs. then.
