"go to sleep","FACK", "puke" all by eminem
"i wanna fuck you" by akon
"let the bodies hit the floor" by drowning pool
"life starts now" by three days grace
if its a woman that just died, playing "sexy *****" by david guetta would be a bit offensive
basically anything made by mindless self indulgence, "get it up" and "masterbates" come to mind first though
"dying to live again" by hedley
"all you did was save my life" by our lady peace
"cigaro" by system of a down
"take this life" by in flames
"call it karma" red jumpsuit aparatus
"show me your genitals" jon lajoie
rave music, trolololol'ing or just rickrolling the funeral would also be perfect
yes i know im a bad person
