I just stopped listening to the music I was at the moment. I might just be freaking out for nothing though.
EDIT : just talked to a friend doing medical studies and he told me this : When you eat chocolate, take drugs, etc... you ingest something and the body have to deal with it. Stuff happens and you can't really control it. But when you listen to music, you activate something through your sense, so the brain can regulate it (for example when you start listening to a song and you love it, then the more you listen to it the more it annoys you until you just ignore it when listenning to it. Brain regulated).
I like his explanation.
