You've Got So Far To Go - Alkaline Trio.
I like this one because I think it is very rare that a punk or rock type band (nowadays at least) has a love song that is genuine sounding. All the new pop-punk, pop-rock bands have lyrically stupid songs and have them in abundance.
This song is just great. This line especially gets me:
"I heard everybody's voice cut out when you spoke
And I watched all the lights go dim
when your eyes opened"
Oh man....
