With all the recent talk of your music and files moving to the cloud, QNAP has made a way to do it yourself. All you need is one of their NAS (Network Attached Storage) devices and download their Android app QMobile and you are set. You can store all your music and other files onto the NAS and access them remotely with the app on your Android phone. They also have a live demo of the App on their website here. Try it out and let us know what you think.
It looks like this app has already been available on the iPhone for some time now, new to Android.
