Most often the music does end up in the movie, and sometimes there's a point where I wish that it wasn't, just because I think the score would be more effective if there was less of it. But, again, that's not my call. ↗
The beauty of a main title is that you establish your main theme and maybe a bit of your secondary theme. You plant the seed that you're going to go water later in the score. And so, having that removed just made it so much more difficult. ↗
You have to write a good score that you feel good about. At least, you're supposed to. But, if the director hates it, it ain't going to be in the movie! ↗
I'm not trying to clock scores in this lifetime, it's just that things are better now than they were like five, ten years ago. Music has gotten a lot better. There's a lot of people who are committed to - soulfully. ↗
