How do you upload your mp3 files to facebook account?

Tweet

So, I just rejoined facebook again, after for a whole year of inactive there. I just have to update my email and password there. I tried to manage my home page on my account by adding some photos and music to it. Although there is music tab I can add to it, but I can't upload my mp3 files from my hard drive to the page. So, how could I do it? Can anyone give me some advices?
