Well, I don't know if this is the same thing you're describing, but I've found that the album I listened to three years ago is not necessarily the same album I hear today even though it's the same album. I've only been listening to jazz for a little over six years now, so I'm not sure I can assume I know any work, even one I've listened to many times. So if I'm talking about a work that I haven't listened to in a couple of years, I don't know what I'm talking about. On the other hand, I imagine this musical growth will keep up, so I don't know what I'm talking about now from the standpoint of three years in the future. Look, just to be safe, assume I don't know what I'm talking about...
