these two links online show the 7 day free trial for apple http://www.siriusxm.com/ios and http://www.siriusxm.com/oniphone/indexi.xmc
maybe if your app has a feedback option you could send them a message and mention the issue you saw.
I hope the on demand also has the shows that aren't just interviews, like some of the 2 hour dj shows that run at night. I think its just great, with all the constant talk about competition from Pandora, Spotify blah blah blah etc sirius xm shows anyone can enter that field, but what matters is the content.
I've been reading some comments about slacker etc and overwhelmingly people say the experience gets old, they want to hear a live dj to feel connected with the world and even the choice to pick your own music gets old when the app wont change based on holidays, day versus night programming and shallow playlists. Mine is that pandora playlists jump around to what I know shouldn't be classified as my choice.
Like one person said the classical music channel on Slacker repeats the same music, plays only parts of scores etc....basically, songs don't fit.
I like this on demand, I checked it out. Can't wait. Alot of new subscribers don't know that mid day its mostly commercial free popular music like FM, though uncut and explicit language,. But the morning, evening and weekend shows are what I have it for. Luckily with my xmp3 I've been able to record them and listen during the day.
