I don't really think there is any sort of universal music survivors look for, because were people, and different people people have diffent tastes and needs.
I mostly like strong angry music, like heavy metal and hard grunge, but not just screaming crap with no feeling. Some Iron Maiden, Metallica, Black Sabbath, Alice in Chains, that sort of thing. It makes you feel kinda like you have a right to strike at those that hurt you, and to be angry and primal without feeling guilty.
Sometimes i like stuff that is less angry, but more like defiant or free, like Bob Marley, Jimmy Hendrix, Led Zepplin, Tom Petty a few things by Neil Young, mostly rock from the 60's and 70's. If hard rock makes you feel strong, then this kind of thing can make you feel indominitable, if your in the right mood.
And if your really feeling low, theres always music that seems like it was made from the darkest pitts of the human soul. Sometimes your better off not listening to it, but other times it lets you draw strength from places you normally can't, and most people think your not allowed. Nirvana, Korn, Marilyn Manson (Yeah i know, but he does have some good music), The Alice In Chains self titled album, and some of that stuff floating around on the radio recently is pretty good for that.
I guess if you don't really like rock, some classical symphanies can inspire the same feelings, but i don't really know who does what there.
If nothing else, just listen to something to put you in a good mood, like sublime, Marley again, Led zepplin again too, generic 80s rock or any other pop type music you like to listen to is good, but pop music is too damn diverse to start listing off bands.
Hope that helps. Later.
PS i think i'm going to Ozfest this year, so if anyone else is going, let me know, maybe i'll see you there.
