Mp3 Player - loading songs from user computer

I’ve made mp3 player. You can see it [here]

But if you try to load any of custom play-list from your local PC - it wouldn’t work. Does anybody have an idea why?

When I run this mp3 player on computer (not from website) - everything works.

May be there is kind of security issues, that prevents flash from loading local files data?

ADDED: I’ve found some info [here] . I’ve used FileReference already to load xml file (and it loads xml, but not mp3). I guess I need to make some changes to the code, so the chosen mp3 file would also be loaded through FileReference object.
