you've got an awesome melody starting, but if you got a person singing in it then the drum beat seems a bit impetuous. if there's a main melody that isn't the drums, then everything just becomes the background except for the melody (in this case, the singing). i just think that the drumbeat seems a bit of a distracting background for the singing right now, but lemme know when you finish it.
I've been working on it, and i'll see where i get when i add the vocal element. as of right now, the drums work really well with the song, so i'll stick with that, but i can't seem to transition from the strait drums feeling into the sort of swingish roll beat at the beggining, so i would have to change it anyways. Stupid newgrounds won't let me upload the newer version, so i'll have to show you later :P
