needs work

ummm... dude the thing is I think you need to work on is being true to your listeners, you can't keep saying you're gonna kill everyone and actalltough and all, because you can't really back it(in my opinion) also the lyrics need work man. Anyway
Keep it pimpin'
BN out

Not bad

Background music = Really good. (did you make the background music?)
Recording = Sounds a bit staticy...maybe try recording a little further away from mic and put recording volume down...then after turn it up for the song.
Lyrics = The swear words really ruin it...no offence or anything but i find that people just normally swear in their songs to make it cool or somthing...which really is pretty dumb...However it did go with the song in sync with the beat so thats good.
Effort= quite good. I dont normally work with lyrics in my songs and it normally takes a while for the recording and stuff so i realise the effort put into this.

Overall = Its not bad if it didnt have the swearing it would be a lot better.

Keep it up! =D
