From what I'm aware, iTunes cannot be set as the default player for LW in OS9 (only OSX.) So after dwnlding, within iTunes you'd need to add (CMD+O) the mp3s to iTunes Library from your dwnld folder. Make sure you know where your dwnld folder is & its path (keep an alias of it somewhere easy to find such as in Apple Menu Items & Favourites or your desktop.
Are you sure these aren't mp3's & are just missing their icon. See this thread: http://www.gnutellaforums.com/showth...threadid=27265

Are you sure you're choosing an audio search. If you do you can add More Search Options by ticking the box. This will help to eliminate unwanted results whilst giving you a better cahnce of finding specifically what you want. You can even add .mp3 to the end of the search title (particularly if you're doing a general search. If this doesn't solve your problem get back to us here in this thread. Good luck.
