They say you get your whole life to make your first album, but your second, only a fraction of that. Which I think speaks for how many first albums are better than their follow-ups, if not much of the music that many artists release after they initially debut.
The truth is, it’s very rare that an artist’s music gets better with age. Most musicians peak early. I don’t have any science to prove this, I just know that it’s true. I think most music fans would agree (but then, this is the internet, so please do, tell me if I’m wrong).
