Bursting Lungs: Loud music can be hazardous to your health:

Environmental pressure swings may cause air leaks as a result of transpulmonary pressure changes across areas of trapped gas in the distal lung. This is the first report of music as a specific form of air pressure change causing pneumothorax (five episodes in four patients). ..... we speculate that repetitive pressure changes in the high energy-low frequency range of the sound exposures is more likely to be responsible.

I've heard of loud music damaging ears, but this is the first I've heard of it collapsing lungs.
