I can't believe your post has not had any replies. I liked your post. Could that also explain why when I go shopping and certain types of music are played..I get a headache and I have to get away from it? I go to this one certain store..I have gone at different times etc...and EVERY time I go in it's quiet but as more people come in..then the music starts and just ruins it for me. haha..makes my husband happy though. Sorry myth..just saw your post after I posted.
