Interesting idea I never thought of...
Great list of music posted so far. Please post a Youtube video for your songs if you can, as I'm getting a huge kick out of listening to all these great options.
Since I've never put much thought into this... I might come back and update this at a later date.
R.E.M. - It's the End of the World
Joe Walsh - Life's Been Good
Beatles - In My Life
Blue Oyster Club - Don't Fear the Reaper
Simon & Garfunkel - The Sounds of Silence
