Well, there are certainly original things to say. But I'm not sure that a pop song is the appropriate format to say them in.

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.

If you want to write a love song, you need to not try to write it for a particular person in a particular situation. It needs to be vague, otherwise you're going to fall into trap after trap of trying to rhyme with somebody's name. Keep it vague.

If you start out with a song sounding like Britney Spears, and you end up with a song sounding like Pauline Oliveros, you'd better have pretty good liner notes explaining what on earth you mean.

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

When you're making a singular pop song, you don't really need any subject matter. You just sort of say, "Uh, I love you." And then you try to figure out some rhyme for that, and there never is one.

That seems like one of the differences in expectations of "serious" and "popular" music that you can actually depend on the liner notes to explain yourself? Yeah. Whereas in popular music you depend on photo shoots. A hardcore band who looked like Duran Duran would have to depend upon those liner notes.
