ID3 Tags

Ok, I know the new flash player handles ID3 tags. I also kno that yhe whole song must be loaded in order to see the requested ID3 info. I need help on adding a preloaader to music that is loaded dynamically via _root.newSound. They are obviously MP3’s. How ouwld I go about adding a preloader, and getting the correct ID3 info into a text box. Thanks in advance.
