There are songs that are one big crescendo. An escalation from the first note until the very end. I prefer songs that earn their emotional catharsis, whether its at the end or someone else, it takes the song somewhere extra special. I have compiled a list of songs I enjoy that do this very thing.
Silver Spring - Fleetwood Mac
Silversun Pickups - Lazy Eye
Mumford & Sons - The Cave
Muse - Uprising
Smashing Pumpkins - Mayonaise
M83 - Outro
The War On Drugs - Red Eyes
The Killers - All These Things That I've Done
Coldplay - Fix You
Fuel - Shimmer
Bush - Glycerine
Candlebox - Far Behind
Puddle of Mudd - Blurry
