'Sorcerer Radio' is quite good.
Download the free app through the Apple Store to a mobile device or iPad / tablet and enjoy !
They play a nice variety of Disney Theme Park music from ALL Parks....and ALL possible related music.
Everything from background music, live staged Shows, various Parade soundtracks, Attraction scores ( past and present ) plus numerous area music loops, and a lot more.
So it is much more then just your typical playlist from common officially released Park albums.
Dparkradio has a great app
Sorcerer radio has both and app and website that I really enjoy.
youtube has a lot of different loops I like to listen to
reedycreek has an app, I haven't listened to it in a while. They've been playing a lot of DLP & TDL and I'm not a fan
d-cot.com has a lot in their jukebox.
