I don't like music at all. I have an ipod that I listen to at night sometimes or in my car when I'm driving to work, but I never take it to the gym since I like listening to music in a controlled environment. I'm very hard of hearing, so when I'm hearing unknown sound, I tend to focus on the sound to determine what it is. So one day at the gym, the music suddenly changed to some rap music - not that I have anything against that type of music - and I suddenly had to look around to zero in on what sounded like an alarm. Then I realize it was the music and I was able to focus again. So basically, while at the gym, I don't hear anything. You could be talking to me, and I wouldn't hear it because over the years I've learned to zero out sounds completely and only focus again when I hear something unexpected of the current environment. I got several complaints over the years about people talking to me when they see me in public, but I always try my best to explain my situation.
