The song that saved my life is "Bullet the Blue Sky". Not the lyrics, of course, but the general mood of the song. I was in a dark place for years and rather than becoming crazy I learned the guitar trying to play that song.
I saw a documentary once, of a guy who blamed U2 for having persistent tinnitus resulting (according to him) of a Zooropa show being too loud. Of course he had a hard case since he was the only one suffering from this after the show (I believe it was Marseille, I was seated in the stadium). But to illustrate his pain, the TV crew kept editing images of the guy running and "Streets" with a distorted sound.
I felt sorry for him though, because tinnitus is terrible.
