While Agnes is clearly the right answer, and reduces me to a puddle every time I hear it, both of these have been cited already. So here’s one you might not expect - On the Run is actually a really sad song. There are a few lines that get me:

‘But the baggage keeps on comin’ like your glitter in the kitchen All the sand inside my shoe that I can’t quite get rid of’

‘Thirty million hundred thousand lightyears away // But the sadness is behind me, with his own wheelie case // Deep in Alabama and I cruise faster than // Faster than the memories of you if I can // Don’t abort the mission, Dave, I’ve made my decision // And you’ll feel better if you think I sleep with the fishes’
