I've said this before. I'll doubtless say it again: "Expectations are the devil."
My problem with "reaches a certain level" is that reaching a level means that the new piece is already fulfilling expectations. Is already in certain ways familiar. Successive listens will likely simply confirm those expectations, strengthening them. OK as far as it goes, but what if a new piece does not fulfil any expectations? Does not reach "a certain level"? It is too likely then that the piece will be deemed unclean and cast into outer darkness. As it were. Whereas it is more than likely that the problem lies with the expectations, not with the piece, and that overcoming (jettisoning) the expectations can lead to enjoyment of pieces that would ordinarily never reach the magical level. Ordinarily being the ordinary condition of having expectations. Of having expectations so ordinary that they pass without even being noticed as such.
In my own listening, I have had to confront my expectations over and over again. Over and over again, I have heard pieces that did not meet my expectations for what I liked or wanted or even considered to be music. Over and over again, I have come to enjoy, to love, to prefer pieces that I had previously rejected. Right before Christmas last year, I was diagnosed with cancer, so had to leave Europe and come to the US where I had medical insurance. I moved in with the friends who had become the custodians of my most precious books and CDs. Since then, I've been going through my four DJ boxes, again, this time ripping every unripped CD, making no decisions about whether I really thought I wanted this or that piece or not. Everything.
It has been embarrassing. CD after CD of music I know I didn't like 10 or 15 years ago, music I knew I'd never care about, turning out to be captivating and essential. No expectations, hearing the music as far as is possible as it is, not as I want it or need it to be. Embarrassed, but happy.
It's not a hundred percent, of course. Some things I will never like, and that's OK, too. But so many things I've thought of as unlikable that turn out to be altogether lovely and delightful that I feel I should probably never say "some things I will never like" ever again. I just never know.
Well, I gotta go, now. I have a lot of ripping to do. The cancer is retreating nicely, but I don't want to go home until I've ripped every single one. Ta.
