Happy Valentine's Day! We asked you which Radiolab stories are the most Valentine-y, and these are your top picks...all in a handy-dandy playlist.* We've got a message from Ancient Greece, some parasites, a seductive chatbot, a beguiling leopard seal, a falling out of love tale, an interstellar mixtape, and the epically romantic story of Emilie and Alan. Enjoy!
