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 ?

PC Players make it a pain to correctly fill in the metadata, therefore it is generally easier not to bother to have a clean, well-organized collection.

My favorite media library is my filesystem. I use a bloatless, instant open media player - Media Player Classic, which has all the features I need and more (alternative splitters and codecs, channel remapping, web server for remote control, custom keys, etc.), and none of that bloat. It's not smart to be tied to a particular program, it has gotchas - they go commercial or change something and once you have to update something (codecs, OS, etc.) and your old player won't work, you're fucked. I could change player tomorrow, and keep my clean, well-organized collection where it is. Besides, playing music is a background task. I don't want 20+ MB shit on my system. Perhaps this is why everyone says their computers are slow/unresponsive/bloated/infested and they need so many upgrades so often.
