Just a quick post (I swear).
Just recently (meaning, around five minutes ago), I saw that I can also build a widget, provided by Box.net, to display certain files from my account. And, if they are music files, you are able to hear the song from inside the widget. Have a try, it's in the sidebar, in the "More About Me" section.
For anyone that is reading this from inside Facebook: go to my blog; it'll make more sense there.
Remember: it is comment-ware music. If you hear it, just comment in this post with some feedback about it.
