You just need a week of practice. That should do it. If you are afraid of cli, then download and install webmin in your server. Believe me, it's very easy to do. Just copy paste (obviously, check what you are pasting first. Don't download a virus please) from tutorials.
You could serve your mp3s (considering they are legal ones) through an external cdn. Shouldn't cost you an arm and a leg. For the site, it can be as cheap as $6; depending on the plan. a 2GB vps is 10 times better than those shitty cpanel hosts with every kind of limit possible, and shared ips.
Edit: FYI..

Install webmin on your ubuntu server (be sure to disable webmin when not using. That will make sure that the service doesn't eat your RAM up):
