i have been looking through all the internet,i just can't find it,i searched on YouTube,Google,DeviantArt,Team17 Forums,etc. and found NOTHING,i only find the music from the PC Version,can someone tell me where to find it?:(

IDK about N64, but this thread has the high-quality PS1 music (http://forum.team17.co.uk/showthread.php?t=32314).

The link in the original thread is broken. I posted a mirror link at the end of that thread.

for future searches: music streams audio playstation psx WA armageddon

I've tried searching too - there's nothing to be found.

All you can do is record the music from your TV or an emulator. (I did that for the awesome menu theme once, but I lost the file & my current PC doesn't have a good recording function.)
