I was just listening through one of my playlists, and I realised just how much a speech sample can add to the depth of a song. I personally think this technique is underappreciated, so here I want you to post your favourite song which uses spoken word samples, be that from a speech, or something else!
Mine is Gyre by Nothing More, which uses a clip from an Alan Watts lecture:
I guess David Byrne & Brian Eno's My Life in the Bush of Ghosts introduced me to this technique. But, for me, Steinski was the first master — if for no other reason than he was doing it in the day when he had to splice the tape rather than sample digitally.
