This is not an exaggeration, and I'm not saying I have not done it before myself because I have (my ears started ringing and it did hurt). The issue is that it really is deafening not only the music but the singing along that is somehow louder, and ever since that first time i hurt myself i have grown weary of loud music (And i already know about the "because they enjoy it more" argument). Can somebody give me a psychological explanation of the need to do this?
