Pretty simple: They just aren't as good as they used to be.
Not a big deal, they're approaching their 50's. Can't keep it up forever. Everything has an expiration date.
I disagree - both with you and, to an extent, Bono.
I concur that the album was, well, an album. And that this material is not the typical sugar-coated pop music, some of which U2 created on their last two releases.
JT is also not one of those albums - but times were different then. U2 were able to get a huge album and a string of hits from songs that really weren't typical pop music of the time. Even the haunting WOWY - a "love" song that usually do succeed on the charts - seemed a bit out of place compared to Michael Jackson, Bon Jovi, Debbie Gibson, Poison and the like of 1987. But I would contend that if U2 were to release JT today, it would not be the hit album it is. And not because of U2's age, but because people don't buy albums.
NLOTH is a fantastic album and easily one of my favorites. The songs are diverse (unlike some of U2's work - I'm looking at you, JT), and while there are some pop hits (like "Crazy") there are also flat out rock songs, soaring anthems, and bluesy epics. For U2 to have created an album like this at this point in their careers is mind-boggling. To say that they aren't as good as they used to be is incomprehensible to me.
That said, Bono is right, this album is a bit challenging and I can accept that some may simply not like it. There aren't the big hooks in the songs that U2 are famous for. This is an album not meant for the masses.
Still, when I went to the concerts, I could see people reacting to the new songs - songs that some clearly were hearing for the first time. And the audience reaction was great.
The trouble is that people don't buy music any more. So far, no album released this year has sold 2M copies in the U.S. That is incredible. In 2000, albums would sell 10M copies just in the U.S. But thanks to illegal file-sharing, people just download an album. iTunes has helped, but now people "cherry pick" songs, which also hurts album sales. Some artists have huge iTunes hits, but their albums flop.
Bono, and the rest of U2 - including their management - have to accept this change. NLOTH has sold over 1M copies in the U.S. - one of about 8 albums released this year to have reached that feat. Worldwide, it is the #1 album released this year, even though it has sold only between 3.2-3.8M copies (depending on which source one uses). For the #1 album not even sell 4M copies despite it being almost November - in a year where juggernauts like Eminem, Kelly Clarkson, Bruce Springsteen, Green Day, etc., all released albums - says a lot.
Bottom line - U2 didn't have the big hits off this album that they hoped. I'm not sure why. I can accept that some didn't like GOYB, but "Magnificent" should have been a huge hit. It's lack of success almost has me buying into that conspiracy theory about radio boycotting U2 (due to some comments Bono made about radio paying artists for playing their songs). But album sales have been strong as they can be, given the times. The tremendous success of the tour - even in "smaller" markets - shows that this isn't 1997. U2 can do stadium shows worldwide. And I hope U2 take this and don't produce another album full of potential "singles". That was a fun experiment for ATYCLB, but we don't need it again.
