DISradio had been my favorite of the Disney streamers for quite a while; Pete's playlists always seemed to be more to my liking than any of the others.
However, since then, I've settled on Magical Mouse Radio
to give me my Disney fix. That's not to say it's second-rate, though. Mike seems to have that knack for knowing what to play next to keep me entertained, just like Pete did. Last week, he even took requests via Twitter and played them live, with DJ-style voice-over and all. Yeah, real Internet radio!
Give Magical Mouse radio a shot on Live365, and follow @BeOurGuestMike on Twitter. You'll love it. (Makes me wonder when the guy actually works, though)
I have started listening to more of the options available, though, including many of the ones on SisKaren's list. Sorcerer and MouseWorld radios are always good fallbacks for me.
I've also signed up with D-Cot, and have been streaming some from their jukebox, but it's less than ideal on my Android since it won't play in the background. It does need Flash installed, so it may not even work on an iOS device (just a WAG, I have no way of knowing).
