Well, there a variety of tunes out there with understated music and methodical sampling of the human voice like that for effect, although usually they try to provide something a little more concise and deliberately narrative to go with it -- limitations of the medium. I'm pretty out of touch with the usual channels so I can't actually name any of it done in the past 40 years or so, but here's some classic Simon and Garfunkel overlaying Silent Night with a really depressing 7 o'clock news: https://www.youtube.com/watch?v=WgYFXCUEL4Y
Also, every so often you hear about a crazy fire going on or someone trying to jump off the Golden Gate bridge. (On sf-1033, naturally, not this one. Also, I like what sf-1033 does with the reverb on the police scanner bits.) It was really great back when people were rioting in the streets after the World Series victory, throwing bottles at the police and burning an articulated Muni-bus.
For a more recent example, Manu Chao also samples a lot from similar sources, like radio ads, movies and political speeches (usually in Spanish). E.g. in Welcome To Tijuana: https://www.youtube.com/watch?v=qw2Pny_N_Tg&t=2m30s
