Original Soundtrack composed by: Jeffery L. Briggs, Ken Lagace and Roland J. Rizzo
Amiga Soundtrack by: Allister Brimble and Anthony Putson
"Love Forever" is one of the "Independence Tunes" that you might hear while playing Sid Meier's Colonization. Indeed, the goal of the game is to eventually declare independence from your mother land, fight a War of Independence and win it - no easy feat! I'm not quite sure why a military marching theme is called "Love Forever" but hey, there you go.
EDIT (15/10/2016): A fellow YouTube user +Plastiware has alerted me to the fact that despite me originally advertising these tracks as the Amiga version of the soundtrack, it's probably not entirely accurate. I originally marked these as the Amiga version due to the source MP3s I used stating Allister Brimble and Anthony Putson as the composers, but when comparing these tracks to Amiga versions of the soundtrack on YouTube and then comparing it to a DOS CD version, it seems these are most likely from the DOS CD version. Apologies for the mistake.
