What makes us fall in love with a song? What makes us want to write our own songs? Do songs help? Do songs help us live better lives? And do the lives we live help us write better songs? Featuring over fifty songs that have both changed Jeff Tweedys life and influenced his music - including songs by the Velvet Underground, Joni Mitchell, Otis Redding, Dolly Parton, and Billie Eilish - as well as thoughts on Jeffs own songs, World Within a Song asks why do we listen to music, why we love songs, and how music can connect us to each other and to ourselves.
