Either Josh Groban's "February Song" if it was a tragic death or "Not Falling Appart" (Tiesto Remix) by Maroon 5. Most likely the latter.

Stone Sour --Reborn

THE LAST BEAT OF MY HEART- Siouxsie And The Banshees

or

ATMOSPHERE- Joy Division

for the moment I'd choose Paradise Lost - The Last Time

until I find something better

"Cosmic Journey" by Solange Knowles :Dinah:

Perfect song for the unknown life after death
