Well, I checked out FLAC, I have it on my 'puter now. It looks like from what I've tried, that you can't convert MP3 files to FLAC, only AIFF so far, probably WAV to, but I couldn't do WMA ether... And I can't play FLAC files, through WMP, iTunes, or probably anything else I have.. I'll try them some time. So, so far, it looks like you can use the files to send to people, and you can change it to AIFF or WAV once you get it, but that's about as good as it gets, much the same as using Cocoamonkey, and APE files. So it's a matter of using what everyone else has I guess. Which is APE. But still, looks good as a back up.
