" Three out of five UK adults don't believe that musicians should profit from their singles" ..... etc, etc
I don't believe for one minute that three out of five people would say that. Of course we don't know exactly what was asked or how the questions were phrased. One thing that I am certain of is people do think musicians should be rewarded for their endeavours (Note, I said the musicians). What people do object to is the amount creamed off the top of their earnings by uncreative people sat in offices.
