I'm coding a system to cycle through different music tracks of the right mood for each situation in Heat Signature - 'peace' and 'tension'. The trouble is, Ivan's tracks are 6 to 9 minutes long, so I'd have to wait that long every time I needed to test whether it correctly changes to the next track when the song's over... So I had to write and record 4 new vocal numbers myself. Tried to keep the running times short while still conveying the full atmosphere of the game.
