He said: "I couldn't write a song, an album like 'Definitely Maybe' now because the songs are about being 24 and cigarettes and alcohol and all that, you know.
"And you just don't feel supersonic at 10 past 7 in the morning changing nappies. You know, you just don't, it's as simple as that."
The rocker admits it can be difficult maintaining an audience as success grows because fans can no longer identify with the experiences musicians write about.
He explained: "When you start off, I was 24, your audience is 24, you're all in the same circumstances, you've not yet become a rock star, so that's when the magic happens, when you're writing songs about their life and your life mirrors theirs and visa versa.
"Then, as you go on, you become richer and more famous and all that, and they kind of stay the same, and you kind of lose that magical connection that you had, so you have to write about different things.
"You know, eventually your time passes, and then youth culture changes and something else comes along, you know, that's just the way it works."
