Music

There's also music in Nexuiz. Current tracks from the game can always be found in http://svn.icculus.org/nexuiz/trunk/data/sound/cdtracks/ .
Older tracks can be found at: http://ouns.wikispaces.com/music .

You may occasionally hear music that's not in the game itself, but in a map or other package that was downloaded to your dlcache folder. In that case, the fastest way to find it is going to the folder in your file browser (Explorer, Konqueror, etc.), switch to list or details view and sort by date. That way you can see what was recently downloaded. The PK3 files are renamed zip files, so just open or extract them. (don't leave the extracted content in dlcache)
