Do you mean "sounds better than other genres when in recorded form"? or "has had the most care expended on the recording process"? If it's the first, I've always thought (with no evidence, of course), that part of the "early music" or "original music" or "historically-informed performance" trend in the 80s and 90s was supported in large part because that sound was ... let's call it 'most striking' in early digital recordings. The early cd's of these groups sounded worlds better than many of the routine muddy and careless vinyl recordings they replaced.
What genre tends to be recorded in the most satisfying fashion?
I vote for Fado and string quartets. Of course this is a fairly meaningless generalization, but I'n curious about what anyone else thinks.
