Not a huge fan of Blast but their music will suit the csgo pro scene as a whole
punk/metal in general but my favorite is just plain replay without special effects
music style doesn't matter, but editor has to sync the video to it
depends on the edit: if every shot is synced up with the music - probably dubstep or some trap beats, for basic/hltv type frag movies - maybe dnb, metal?
why you dont need sound? got wh? :)))
