If you check the credits for VF3, you'll find the name of the composer.
So Mike Raznick is the composer
It's great to know his name and peek at his other works. I found out that he's multi-award-winning (totally deserved) and he previously also worked on VV4 and Fish Tycoon 2! What about the older games? Did he also compose for Plant Tycoon? That's my favorite LDW game in terms of music.
