The first track, titled simply Operation Spectrum, serves as the theme of Contingency Contract Spectrum and is used as the BGM of C.C. Spectrum's menu.
The battle theme, which is used as the BGM of Arena 8, is titled Operation Spectrum Battle Theme.
Excluding the unreleased themes of Contingency Contract Beta and Barrenland, Operation Spectrum is the only instrumental Contingency Contract theme (if the computer-generated or sampled voices are excluded).
