I definitely have to agree on the silverware.
Bad sounds:
Ticking down timer on a bomb
Cracking bones
I'll add the melodic ring of wind chimes on a slightly breezy summer day (to the best sounds category)
Also, the piano pieces of Italian composer Ludovico Einaudi.
Also, the sound a woman makes when shes going to orgasm (perhaps a little to much info
)
Also, the peaceful sound of waves lapping against sandy shores.
Also, thunderstorms at night and steady rain on a lazy saturday morning.
I could go on all day... These just stick out
