Yes, cinemagic has disappeared from the radio dial. I like pandora a lot, you can create custom stations to play what you want, for example I have a John Williams channel and a Bernard Herrmann channel among others.
Its free though they have a pay option that doesn't seem to offer much. I tried playing it over my smartphone app via bluetooth today and it worked like a charm.
I've used slacker radio and their cinema music selection is shockingly small. You will hear nothing but repeats after a few hours.
