Love of a Lifetime- Firehouse
When I Look Into Your Eyes- Firehouse
I Live My Life For You- Firehouse
Firehouse is an excellent band from the early 90s but few people seem to know about them. They had alot of good songs though. I've introduced a handful of friends to them who heard them for the first time and loved them. Their other most known songs are Sleeping With You Tonight, Don't Treat Me Bad, and Reach For the Sky.
I linked some of them so you could hear the song for yourself and decide on you own. A couple of those video's were shot around 1991 so try not to laugh at their hair.
Anyway, I got other good love song ideas...
Far Away - Nickelback
Lips of an Angel - Hinder
Iris - Goo Goo Dolls
Black Baloon - Goo Goo Dolls.
It really all depends on what ideas you have in your mind for the video. I don't know so I really can't give you the most accuarate suggestion, but those songs there are songs I think are great songs and would love to see made work in an AMV.
