In a few short hours, we'll all find out whether Rosanne Cash will take home a Grammy for "Sea of Heartbreak," her duet with Bruce Springsteen off The List
(an album inspired by a compilation of essential songs her father,
Johnny Cash, gave to her when she was 18). But you don't have to wait
any time at all to get a behind-the-scenes peek at not only The List,
but also Rosanne's brain itself -- from her actual physical neural
functioning, to her thoughts on Sting's tantric sex practices -- by
listening to our podcast of "Music on My Brain," Cash's tune-filled talk with neuroscientist Daniel Levitin at the Museum of Science a few months ago.
