Well yes, underwriting in the respect of playing the music on the radio stations that you and I are paying for, is fine.
It really should have always received equal airing with the classical music that the BBC have decided that we should be exposed to. a large part of the problem is that it has not and it is a little late to do it now.
I will see if I can provide a link to a recent thread called 'Proper Music', which touched more on this aspect.
