In the new action movie "War" with Jet Li and Jason Statham, what is the music playing in the yakuza club?

in the new movie "war" with jet li and jason statham, jet li is seen driving a silver exotic car (spyker c8 spyder), and parks on the curb outside of a japanese yakuza owned club. while he was driving however, some kind of hip hop music was playing very subtlely in the background, and got louder as he pulled up to the club, and at full strength upon entering the club. the music is actually being played by the deejay in the club. i think the lyrics were like "hey hey hey..." it plays pretty much all the way until jet li walks up to the 2 guards at the hidden room and gradually fades out as he cuts both of their throats and proceeds in the room to kill the yakuza members. i want to know what is the name and artist of that song thanks.
