A combination that seems to work great for me is combining Arthur magazine's BASTET music streams with RadioLab's "weird science" podcasts. Try these two streams together:
RadioLab's science podcast on "Emergence":

Arthur Magazine's Bastet stream 4:

Played together, these two may blow your mind.

Does anyone else have some good combos? Is there a name for this audio mashup game?
"Do the ants know she's special?"
"Well...I think they know shes the Queen..."
