FWIW, I think television is completely the wrong medium for listening to music but a great medium for programmes about music.
There is loads of classical on sky though. (was that the right thing to say?)
No, presumably what you didn't do is click on the classical link - you then are given choices within the classical umbrella.
However, it's true that the advantage of not having the classical label is that this would then have to be replaced by a number of other labels thus increasing classical's footprint.
edit, oops I've just seen that you did click on the link. I think we must have seen different things. Loved the Canadian music category.
