what is ogg?

i've had soo many people tell me that ogg is better than mp3, how? i know ogg is opensource, but as long as the bit rate's the same does it really matter in terms of quality? or does the differnce matter in size ?

Not lossless means WAV or FLAC.
Check your words. Loss means it loses. Less means without. Lossless means it doesn't lose. Not lossless means it loses. Vorbis and MP3 are not lossless. WAV and FLAC are lossless, or not lossy.


How are you going to convince us that OGG is good enough to overshadow all the benefits of iTunes+iPod?
Apple uses gay formats, and wants you to convert your files encoded in your choice of format to their gay formats. Most multimedia products Apple did sucked from a technical point of view. QuickTime was always slow and had the worst media players ever. AAC is a bad choice for a musical format. Etc.
