looking for specific grenade kill sound/marker

ok, so i was browsing around yesterday looking for a way to remove gun sounds (waste of time -.-) and came across a video with the "hallelujah" music as the grenade kill with modified markers. can anyone help me find it or maybe even a download for it?

Google crossfire sound modding.

i have been lol but i cant seem to find it again >_<
