Don't know if this is relevant, but when I was younger and had better hearing, I would enjoy banjo or bluegrass music for about 40 minutes before it started to get very uncomfortable. It literally "got on my nerves" so badly that I had to stop listening. I guess everybody perceives sounds (and other sensory input) in their own unique way, and what sounds wonderful to some may be just enough "off" to someone else to sound unpleasant.
