How does minecraft store its music files?

Solution

The audio files come from here, which is just an XML file. They're not encrypted, and the client downloads them as it needs them. Don't do anything naughty, and read through the Minecraft brand guidelines, which covers third party usage of these resources.

Problem

Where does the music files, that is played in Minecraft, get stored in the latest `minecraft.jar`? Just extracting the jar-file as a zip-file, doesn't reveal any audio files, only `.class`, `.png`, `.txt`, `.lang` and one `.bin` file for the font glyphs. How does Minecraft encrypt the audio files?
