There are two jazz pieces I like--"Take Five" and "Blue Rondo a la Turk." In both cases there is a perceivable melody, and for lack of proper term, a structure. Most jazz to me (and I grew up hearing it all the time) sounds like wailing without benefit of melody, or purposeless tinkling and twiddling, as as for harshly blown saxes, it has the same negative effect as screaming, distorted amplified guitar does--just hurts my ears, crosses firmly from music to noise.
