Beni gave an excellent explanation, but I should also plug my own Vorbis 
introduction, which spends a fair amount of time discussing bitrates.

As to why it is variable in Ogg Vorbis, the short and sweet version is 
"because some passages are harder to encode than others, and it's foolish 
not to 'save' bits on easier sections so you can use them on tougher 
sections instead."

"Christians and their opponents again and again expect that some new
discovery will either turn matters of faith into matters of knowledge or
else reduce them to patent absurdities. But it has never happened. What we
believe always remains intellectually possible; it never becomes
intellectually compulsive. I have an idea that when this ceases to be so,
the world will be ending."
