La, la, la, I have music blasting through my headphones and would get hit by a train if one came along right now because I can't hear anything, la, la, la...

Actually, that happened to a guy my husband worked with. The guy would walk to work along the railroad tracks with his boombox hoisted on his shoulder and the music blasting in his ear. Sure enough, train comes along and he didn't hear it. It took his arm clear off. He came back to work eventually, and he had a hook.
