Going along with the idea of playing songs that aren't too depressing, I would definitly recommen "rooftops" by the lost prophets. The lyrics are absolutley perfect for someone who has died too young. Here's some of the lyrics....
When our time is up
When our lives are done
Will we say we've had our fun?
Will we make a mark this time?
Will we always say we tried?
Standing on the rooftops
Everybody scream your heart out.
Standing on the rooftops
Everybody scream your heart out.
Standing on the rooftops
Everybody scream your heart out.
This is all we got now
Everybody scream your heart out.
All the love I've met
I have no regrets
If it all ends now, I'm set
Will we make a mark this time?
Will we always say we tried?
