Audacity is a freeware programme whereby you can open any music track & edit it so you can grab the sections of the podcast you want & put them in with your own play-list. I've taken the warm up & cool down bits to use with my own play-lists when doing a longer block of running. However I can't see a way you can separate her voice from the music for the parts when the two play together, perhaps someone more technically able knows if it's possible to do.
