Listening to users for ideas works well in plenty of scenarios, but there are also plenty of other scenarios where the users won't suggest something innovative because they don't have the same persective of opportunities as the developer. The best situation is where the developer is also a user of the product.

However in all three situations (idea by users/developer/user+developer) you can easily fail if nobody wants to pay for it. You can find millions of people who say they want a better messenger app and they have plenty of ideas of what features their dream app has. Will they pay for it though? Unlikely.
