7, but only because it's a first attempt
What I don't like is that you didn't bring out the original melody of the "yea-ea-ea-ah". This way it's too monotonic. Good bass though, and btw, responding to click-click-pow's review, this one is in fact not quite hardcore, but closer to dance than other genres. Definitely not drum n bass. (As for me I submit my hardcore songs to miscellaneous, with a [Hardcore] label after the title.)
