It's there, but... it's nowhere near the level of "good". In fact, it's not really even that decent in its current state. I can recognize the tune just fine, but the desperation is taken out and instead replaced with a dance-track feel. It doesn't suit the theme at all. You took out what made the song a hit and instead stripped it down to a very, VERY basic form, which, in all honesty, ruins it. Since this piece is almost 9 years old, this review is a bit of a moot point, but hopefully you looked back on this and gave it another go.

Hm... well I got to admit this is a nice touch to the Doomsday but I agree with Doragon.
Without the sudden feeling of urgency you get from the manic energy from the original... well...
It's great, but it's not excellent.

As a fellow Sonic Robot, I'm trying to be as nice about this as I can. But maybe spice it up a little with a slightly faster tempo, and you'll really have something worthy of Mecha Sonic. If he can go (Semi)Super, then so can this song. But don't settle for (Semi)Super or standard Super. Go for HYPER, my brother. I know you can do it, we were designed for greatness... and the death of that organic blue abomination, of course.

Argh!

Sorry man, but taking the manic energy out of Doomsday just...
Argh! >_<; It doesn't work man.

Haha...

I feel somwhat trippy after listening to that...
spinning around and around...heh

What I tink

Yes, you could of done better and it feels slower. Try focusing on the guitar a little more and lowering the drums and piano. Also add more of the fast note parts. That should seem to speed it up. I mean you hear BUH chee DA DA Buh chad DA DA..
Realy it revolves around the DA DAs. The Da Da is guitar. So yeah.
