I think I have about 15 music channels (some American, some UK) and all the scheduled channels are the same - you are channel-hopping and get ads, ads, ads, ads, ads, real TV, ads, ads, real TV rerun....
The request channels are not much better, since the only people who seem to use them are bored teens who request the same songs and bands over and over
I would really like to see some innovative music channels.
