To add to what SpaceWhale said... or emphasize... Just making music is not enough, you will never (and I mean never) build up a fan base if all you do is create music and expect people to just miraculously find you.
Even if you make really damn good music, that alone is not enough to build your fan base... it helps, but it won't do all the work for you.
You have to push yourself into other peoples view... make use of all the mediums you can handle (As mentioned above)... The more places people can find you, the more opportunities you have to gain fans. And be active in ALL of those communities, just having an account there with some music on it is not enough.
I just took a quick glance at your profile... And I suspect you are expecting too much from the listeners, as you have over 100 submissions... yet only 9 fans. This alone tells me you are not trying at all to be noticed here on newgrounds. Be active, make friends, use the audio ad thread, the review request club, the WIP thread, participate in contests/challenges, ask questions, answer questions...
You have to go get your fans, they won't come to you.
