That's classical music and I'm sure they have their own awards.
I have no moral objection to the concept of MOWOs, it's just a silly idea. Having an awards ceremony which lumps together Chas 'n' Dave with Beethoven just because they happen to be white. MOBO works because black music, as far as I can tell, is pretty much in a similar vein. Rap, Hip-hop, contemporary R&B etc.
