I think this would fit a normal enemy in an RPG, IMO. But the song isn't bad. It's pretty good. I just feel like it could use some work. If you couldn't get it to loop, then you should have made an ending, or a fade-out, instead of leaving it as it was.
Also, for your song thumbnails, try using your avatar. That's what I do most of the time.
I'm going to try to find other ways to possibly fix it before I go about making an ending. If it turns out to be impossible to loop, I will update the song.
Update: Apparently the song does indeed loop perfectly, but there's a problem with the Newgrounds looping feature. I'm not terribly familiar with that kind of thing, so I'll just leave it as is unless someone has a fix.
