Music: Lobotomy (Unused Track)
Composer: Laura Shigihara
Genre: Lostwave (edit: found)
Platform: Fire in the hole

I used inspect element on the PvZ Flash Demo website, in particular an older version of the page archived on the WayBack Machine. There were links for the pages that host the tracks used in the game but also this one, simply named lobotomy.mp4. Best estimate suggests this track would have been used for a fire area that has a lot of holes on the lawn.
