I understand that, but do you actually dislike stuff you've written ?
I have a weird theory about writing music. To me, there is "right music," and "wrong music." "Right music" feels right -- it comes out of my head, unforced, it's fresh, it's "honest" and the "math" of it is there. When I'm in that space where this happens, it's almost as if I'm not writing it -- it just happens. I know this isn't a really clear explanation, but it's the best I've ever been able to come up with. As a lot of other on this board do, I compose in my head -- keyboards, sequencers and scoring programs are for setting down what I've already composed, not for the actual process of creation. Sometimes I'll wake up in the middle of the night with "right music" in my head (my wife hates that). Also like RAMI, I'll sometimes get stuck and fight through a song at the keyboard but it's usually pretty apparent to me that it's "wrong music" and, when that happens, I'll go out, smoke a cigarette and search for the "right music" solution in my head. In a worst-case scenario, I'll leave in a phrase or chord progression that I know is "wrong music" as a place-holder, but I'll always go back and fix it before I consider a song finished. With all of that said, I suppose I like everything that I finish. However, also like RAMI, sometimes a song will bother me for months and it will take me a while to realize what is wrong with it. I won't exactly dislike the song, but I'll know that it's still not finished. Most recently, I wrote a song in an ABABAB form. I liked the As and and I liked the Bs, and I liked the modulations from one AB group to the next. However, the song, as a whole, just didn't do it for me and it bothered me for at least a month. It was only after listening to it repeatedly that I realized what was wrong -- I needed a bridge, so that the song looked like this: ABABCCAB. Once I wrote the bridge and my writing partner and I re-recorded it, the song became "right music" and it no longer bothered me.
I guess I have trouble imagining writing music that I didn't like. Consciously writing "wrong music" seems like a cheat. Then again, because I don't have to earn a living doing it, I don't have to worry about deadlines, pleasing clients, or being commercial.
This is an interesting topic, and I'm enjoying reading what others think about it.
