I like free music. Who doesn't? My unquenchable thirst for downloadable music -- legal or questionably legal -- took a strange turn when a friend turned me onto the archives of the United States military bands. The Air Force, Army, Navy and Marine Corps bands all have their own websites. As far as I could find, our friends in the Coast Guard were left out. Please correct me if I'm wrong. I've been looking for a copy of their song -- the catchiest of any branch -- to no avail.
