Very nice
I've listened to this before, but never reviewed...
I really like this. You stuck on point and kept to the theme and said some interesting things. I like this line "Cause metal rusts, nuts and bolts become one." I think that can pretty much sum up everything if you think about it, nice lyrics
Your flow kind of slurs a bit, but nothing too bad, it can be worked on.
Keep up the good work, I'd like to hear more themed stuff like this, it's interesting to listen to.
