My music yardstick is pretty simple.
If it is - or has ever been - played on a radio station with a top 40/easy listening/classic rock/greatest hits format, there is a greater than 99.9% chance that I will find it totally unappealing, boring and repetitive noise.
This specifically includes artists such as The Beatles, Air Supply, Genesis, Elvis, Daddy Cool, The Eagles, Cold Chisel, Cher, John Farnham and Michael Jackson...just to mention a few who really make me grind my teeth in anger. (I find listening listening to a circular saw cutting through colourbond sheet preferable to listening to those artists).
I dont mind doof (house/trance/electronica) as it makes good background music for mundane tasks such as cleaning, and its certainly better than what most radio stations play.
