I agree that nobody should change their musical style to cater to someone else's opinion. At the same time though, it makes sense to expect suggestions for change whenever you decide to solicit opinions from others. I always say, if you're gonna go cowboy, go-all-out cowboy and unapologetically publish your music to be judged as-is, using your own measure of success to gauge same. If you want to make money making music, judge that success by sales numbers. If success is measured by how many other people like your music, then take the attitude that you need to reach the masses. If success is purely an internal measure, where your music is designed only to please yourself, then I say don't even bother publishing to soundcloud or worrying about others hearing it.
Hell, that's what I do. I make music for my own pleasure only. I make a living via other methods. I tend to not share my music because I don't care what others think. Most of what I create sucks, by my own standard, but every now and then I come up with a track that I actually like to put on the iPod and listen to over and over at the gym, patting myself on the back
Nothing wrong with that.
