limiting file access with htaccess?

[bhuether]

I have a flash mp3 player on my site. The object code shows the url to the playlist. I don't want people to be able to view the playlist. So I tried this:

<filesMatch "\.xspf$">
order allow,deny
deny from all
</filesMatch>

It definitely works, but the flash player can't load the playlist. WHy is that the case? How can I allow the flash player to open the xspf files but deny people from viewing it?

thanks,

brian
