Problem setting up Internet Radio Preferences

When attempting to specify a playlist file in the Radio Playlist field 
in netjuke's system preferences, it comes back with a popup saying:

The directory or file used for the RADIO playlist cannot be found or is 
not writable.  Please make it writable by the web server user, or everyody.

I specified the file:
/usr/local/mp3/playlist.mp3

And here's the permissions for that file:
-rw-rw-rw-  1 www  wheel  0 May 26 15:26 playlist.txt

And the web server's user is www.  I don't understand why it's giving me 
this issue.  Any one know how to correct this?

Thanks,

Taylor
