Books on tape and CD, all the time. I get tons of cooking and housework done while listening to a great narrative.
Also, the sounds of my husband and kids playing soccer in the living room (aaargh!) and their fighting, which I have to run a mile from.
Also, my neighbour, upstairs, is a musician but he plays the same few chords of whatever piece he is learning over and over again. We never hear the whole melody. Drives us mad! It's dirge music, never anything uplifting. Why is this?!?!?!?!
