Also, "Blink" by the Young Dubliners gets an honorable mention, although it's more about a missed opportunity for love:

"Some people say I'm obsessive
To know so much in just seconds
But if love at first sight is a real thing
It just gave me a beating"

Finally, Cheap Trick would have one of the best love songs of all time if not for one word:

"All I want is a place in your heart
To fall into
All I need is someone to love
And tonight it's you"

If not for that one word, "Tonight It's You" would rank pretty high on my list.

(Quotes for all songs named in my previous post are available on request. Seriously--if you wanna know why something's on my list, just ask.)
