It's usually disingenuous when an artist says his or her work is "all for the fans." While that might be true at a benefit concert, artistic endeavors aren't usually completely selfless. Most artists, I suspect, want to find an appreciative audience for their music, but it's understandable that they'd take pride in nailing a double high C, mastering a complex guitar solo, or crafting lyrics about universal feelings in a way no one has before.
Rarely, though, are anyone's efforts all for the fans.
