Kiss of Jealousy
Kiss of Jealousy is the battle theme of the prehistoric chapter, "Contact". It plays during almost all battles that are fought in the chapter, with the chapter boss and optional boss being the only exception.
It also plays during cutscene before the first battle with Zaki, and the second-to-last room of the chapter (until you slaughter all of the cavemen in it).
This song is track 12 on the official soundtrack.
