The Cure - Dredd song, not too much of a sad one, but a song about not giving up which is appropriate in a bad situation lol
or Papa Roach - Last Resort/ Betwen angels and insects, which are just as good
Vanessa Mae - Firefly - very strong emotional violin music, gets me weepin everytime extremely recomend you listen to this one!!!!!!!!!.
Joe Satriani - Top Gun
good music for when youve done a bombing run and you fly away
