There's a whole kind of melancholy that you can only attain with reverb. That's an example of a technology introducing a whole new meaning.

Popular music of the last 50 years has failed to keep in step with advances in musical theater, namely Stephen Sondheim. But the two have grown apart so that popular music is based more than ever on a rhythmic grid that is irrelevant in musical theater. In popular music, words matter less and less. Especially now that it's so international, the fewer words the better. While theater music becomes more and more confined to a few blocks in midtown.

There are only so many instruments you can layer on top of each other that aren't perfectly electronically programmed. "Long Vermont Roads" just cannot be performed live, because it's just too cluttered if it's played by humans. Synthesizers stay out of each other's way in a way that hand-played instruments never can.

Serious music isn't listened to in a casual setting. You don't want to listen to that in headphones on the subway.

I don't remember things initially when listening to music. Like, I don't remember where I first heard a song, I don't have nostalgic attachment to a song in that it reminds me of such and such a time or place. I think I probably did experience that somewhat when I was not a full-time, professional musician, but I don't think music works that way for people who are in it constantly.

There are so many clichés in the world, especially in music, that it's a never-ending creative font to just bring two of them together and let them interact.

If the songs were in lumps, then you would expect to understand what was going on in the plot. Which is not a realistic goal. And also the instrumentation is different for every show, so it's more varied sonically. And people are free to make up their own plots, of course. There are pretty dense and complicated plots, and they're simple songs.
