Musicophilia - music & relationship to the brain

I am listening to Science Friday today. There is very interesting interview with Oliver Sacks.
http://www.sciencefriday.com/
Intro on the site for the interview:
Join Ira in this segment for a conversation with neurologist and author Oliver Sacks about 'Musicophilia,' his latest book. In this book, Sacks, the author of over a dozen books including 'Awakenings' and 'The Man Who Mistook His Wife for a Hat,' looks at the way music and the brain interact. Why can music sometimes remain in the brain long after other memories fade? Why can a person with limited language abilities still be able to sing unimpaired?

This show will be available to listen to online at this link (once it's archived).
