I-War 2 Complete Soundtrack
This archive contains 13 MP3's in 128kbps quality that were once available on the Infogrames FTP for download.
It looks like this is the full soundtrack that was given out by the artist to Particle Systems before the actual release of the game.
This archive also contains samples of the music in Independence War that were available on Christopher Mann's website (96kbps).
And there's an alternate version of the "Badlands" music in it, that was once posted on the Atari forums.
Also, a rip of the trailer music has been put in there, which makes this collection super-complete.
A note on why the music is different (by akula65):
The interesting thing about the MP3s is that they don't correspond exactly to the MP3s that come with the game. If I remember correctly, they have a higher bit-rate for one thing. But some are also different mixes and some may actually be unused music from the game. Here is the correspondence as best as I could make it out:
