When I am planning a Disney vacation I love to listen to Disney park music to get me in the Disney mood!
My favorite site is Subsonic. You can create an account and request songs to play. There are also streaming “stations” you can pick that stream the music of Soar’n or Magic Kingdoms Main Street. Right now I am listening to the Living Sea’s. http://www.subsonicradio.com/
There is also D-Cot and Live365 (search for Disney)
