I think there is such a valid concept as "serious music," meaning that if you don't take it seriously, you don't get it all.

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.

I actually prefer to hear small groups of instruments. Orchestras seem to lack a texture for me, or variety of texture. There's only about ten things you can do with one note in a string section. But a lone violin is continuously changing textures.

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

Yeah, except that when I write pop songs I have pretty strict constraints that I impose on myself. 69 Love Songs is a constraint. That the titles have to begin with "I'"s is a relatively strict constraint. Charm of the Highway Strip is all travel songs. And I am free to change the plot slightly to accommodate something that happens to rhyme conveniently.

I write songs by sitting around in bars, so drinking songs are a little obvious. It's surprising that I don't write entirely drinking songs, since I am, in fact, drinking while writing the song. Drinking and love are the two principal sources of pleasure outside of music. There's only so many sources of pleasure, really. That's about it. Well, there are other arts as well. But none of them are as pleasurable as music, on a physical level.

Surf is that music which is entirely about evoking something. There's never any vocals, so it's not about the lyrics, it's about the reverb.
