Thanks for the comments. The song I'm working on now seems to be sticking to one style, kind of indie rockish.. I may have just needed more time at the piano to learn how to do this. Not that I don't like what I can make with an array of styles, but I agree that it has its arguable downsides (confusion, unstructured, doesn't settle), but not without the upside that it's different and interesting, in my opinion.
