Not hard enough. :\
Let me start off by saying I can't judge this very well, considering I just got a new headset, and this one has WAAAAY too little treble, so I'm not hearing things properly.
Anyway, I really like this. It's good, and the only thing I have to say about it is that it's not "heavy" or "hardcore" enough. I know you were going for a "laid back" feel, according to the description, and I respect that, but the "laid back" feel isn't my cup of tea, I prefer much more heavy beats.
i was trying to get the right speed of the "heart beat" which limited me on the hardcore stuff, i would of put more heavy beats but it was too slow "60 bpm"
thanks for the advice ill be sure to make some more songs with a heavier beat ;)
