hmm
It is pretty fun, your right it isn't as interesting as it could be and it is really short. I personally wouldn't call this happy hardcore although it does have some of the characteristics of the genre. (To tell you the truth I wouldn't try to hard to make happy hardcore, but I just don't like the genre so I won't let that bias effect the score I give you)
What this song needs is a really driving and easy to follow lead to that the listener can focus on something... too much going on.
