Looks like we need an iTunes playlist of music that fits these research results. Put it together w/ some nice noise cancelling headphones (sigh, Bose is $300 ...) and your iPod and sleep your next plane ride away.
If I do one I'll publish it to the Apple site and link to it from this page.
The music group were able to choose from six tapes that featured soft, slow music - around 60-80 beats per minute - such as jazz, folk or orchestral pieces.
Listening to music caused physical changes that aided restful sleep, including a lower heart and respiratory rate, the researchers found.
