Here's the late, great Robert Altman talking about the making of Nashville. He talks about the music, some, too, and the interview (of which this clip is part two of two) ends on this note, so to speak:
When this picture first opened, the people in Nashville, the musicians in Nashville, they hated this movie. They said, "Oh, the music's terrible," and et cetera, et cetera--"they should have used real songs." Well, what they meant is that we should have used their songs. And now that there's a generation past, Nashville is quite popular in Nashville.
Is it? I remember reading a few blog posts here and there from Nashvillians who seem to think the movie is somehow belittling to our fair city. All I know is that I just about crapped my pants when I found out that Gary Busey wrote "Since You've Gone Away," which, oddly enough, does not show up on the LP version of the movie soundtrack that I have.
