If you can't do most of the songs on expert then do not even atempt this. On Expert this song is insanely difficult, and even on Hard it is more difficult then many other songs on expert.
You can also get it on Medium with a near FC. I got it while missing only 3 notes, but it was close. It is fairly easy on the medium difficulty if you can drum on Expert. So if you are having trouble with it on Hard, this is a good alternative way.
