hmm
have you ever even listened to Hardcore? this doesn't sound like it at all.
just because it's called "Hardcore" doesn't mean that it has to be a garbled mess, Hardcore still requires a great amount of mastering and smooth transitions.
don't change the tempo of the song, it just screws it up.
for two great example of what Hardcore should sound like listen to:
"Neophyte Hardcore" by Neophyte
"Mellow Moenie Mauwe" by Bodylotion
I'm not trying to be rude or anything but this just doesn't sound right.
