Eh, I kind of need that thumping noice that plays every 0.5 seconds or so. Bass is really important as well.
Imagine yourself standing in a damp, hot, foggy and hard place. You're surrounded by ry rocks, there's lava floating all over, out of the walls and into huge pools. Machines operating around the clock.
Then compare it to this. it doesn't feel right. I would prefer this in an ordinary cave.
It's a decent start, but this song just doesn't cut it. Add in some of the heavier sounds.
Bass, chorus (preferrably males, as they can reach that low tune that is needed)
And possibly some huge ticking clock. y'know, that Tick Tock that plays in the original song. It's a very important part.
It's a decent try at least, and shouldn't go without compliments. I like it, I really do. But I had expected something else. Not the original of course, some variation is good.
