I Will Dare-The Replacements
I will dare you to come up with a better song that evokes that feeling that you feel- the feeling of love/lust/possibilities that you only feel when you have a glimmer of hope. And it has to clock in under 3:20. I submit it is not possible. The flip side of this song, for the feeling when it all goes bad down the road would be The Buzzcocks "Ever Fallen in Love". These two together cover both sides of the line.
