I hate it when operatic singers 'cross over' to other styles of music it doesn't do their voices justice at all, a bit like putting a ballerina into a pair of hobnail boots. Although I appreciate the quality of operatic singers I don't find it at all easy on the ear apart from the odd one or two Paul Robeson, Mario Lanza or Pavarotti. I would much rather just listen to classical music. But that is just my preference.
