The music stuck in my head at the moment is not really a song, more like a music track from one of my favorite video games (a Xbox game), the menu/title screen music theme is great and so is the rest of the OST, here the music track stuck in my head at the moment:
i've had this one stuck in my head all week. this is one of those songs i liked so much i played it on a loop for several hours, then completely forgot about it. then months later, in a painkiller induced coma after having a tooth pulled, i remembered it. now its back on an infinite loop. terrible vocals (for black metal, too immortal-like), but love the guitar work. also like the trend in entropy-themed black metal ive been seeing.
