1.) I love the sound of a train going through town. I think I've always lived where I can hear the train at least from a distance. I only usually notice it when I'm in bed but it never disturbs my sleep. Whenever I hear it, I just smile and am thankful I am hearing it. I don't know why. I just do.
2.) I love the sound of an orchestra warming up. The dissonant sounds yielding the promise of good things to come. Makes me feel happy.
3.) I love the sound of a rip-roaring, crackling fire. Makes me feel warm even if it's not yet.
