Yes, I have 2 songs which are instant triggers. The first one is Eric Claptan's song "Tears in Heaven." The other is Evanescance "My Immortal." I cannot listen to either song without breaking down into sobbing fits.

About three weeks ago I was in a store and Tears in Heaven started playing from the overhead speakers. I was standing in line thinking everything and anything cheerful I could think to keep myself from crying but tears were on my face and I just kept trying to not listen. I am proud of myself for how well I did, actually.
