Clinton...Ogg is NOT " incompatable with the whole world"...it is simply a slightly better format which is become more widely used every day. A good number of programs are equipped to play it now, and many will record in it and convert to and from it. No, it is not necessary to use it if you are happy with what you have, but that is no reason to call it 'wankerism'. A little reading will show you that it is a top-notch format, and if you DO run into a song you really want that was encoded in Ogg vorbis, it is silly not to be able to get it!
