I'm currently listening to a compilation album of Paul Simon titled Negotiations and Love Songs 1971-1986. In listening to this, I've discovered that the title ("Negotiations and Love Songs") is actually a line from one of the songs - "Train in the Distance."
I don't really have anything in-depth to say about this, but I do think it's really interesting that the title of a compilation album is a line from a song and not a song title. A decent number of the compilation albums I have are titled after one particular song, so it seems that the whole collection is being sold on the strength and popularity of just the one song.
But here, with the title being a line from a song instead of the title, it seems to be more about the songs and what they say rather than just trying to sell an easily-recognizable song.
