Around three years ago, I started a topic in this forum: Should U2 Turn Into A Singles-Only Band?
Over the past three years, much has changed. Albums are even more out-of-vogue than ever. Music is now more easily accessible on a per-song basis through out smartphones and tablets.
U2 have also seen their tour morph into a Greatest Hits show. While physical CD sales are down now, U2 still got their share from re-issuing Achtung Baby which comes with freebies that can't be found through downloads.
The point is that U2 have cemented their legacy. And while they will always need the money to maintain their expenses, it seems more viable to cash-in on their back catalogue rather than make a new album which requires too much time, money, and effort.
There will never be another Joshua Tree or Achtung Baby or All That You Can't Leave Behind.
U2 have also reached the outer limits of what their music is. They are in the damned-if-you-do-damned-if-you-don't stage in their career. If they try something outrageous, it will be seen as a vain attempt at catching a new sound to make it with the current times. If they try something battle-tested, it will be seen as using the same sound all over again. Having been around for over 3 decades puts you in this situation.
If cash is what U2 needs, they can keep doing re-issues, sell their music to TV shows and movies, and do more back catalogue stuff. Less work, and still rake in profits. Remember the last album? It took them years to make it, and across a number of continents. Imagine the costs related to that.
U2's last two tours had to endure delay, which naturally cut away their "private life" time. Perhaps they just need a break. U2 don't need anything to build on their legacy. The only thing they need is a constant flow of cash for their daily expenses and overheads but they can achieve that through less taxing means than making a new album which will pose a lot of risk financially and to harming their legacy.
So now, I ask and this is not from the fan's point of view (of course we want something new!) but more from U2's point of view: Is there still any point in making a new album?
