It's Music to Your Ears...From a Stranger

Take a CD, Leave a CD is more of a social experiment than a business plan, but I love the idea.  I am a not a music maven, but I do love to discover new artists.  The idea is promoting participation from ZipCar drivers to leave CD's at the end of rentals and feel free to take CD's that have been left by others.  It's promoting a behavior to share your favorite new music with strangers and discover the favorite music of others.
