What are some good uplifting songs after a friend takes thier own life?

so my best friend, recently had a really close friend take her life. and she wants to sing a song at her funeral and the girls parents have also asked her to.but she does not know what song she could sing and is trying to see if i can help, i am hoping to find a song obviously to uplift people and not to mourn her death but to celebrate her life. Not sink into sadness over the circumstances of her death and the sadness to drive one to do such a thing, but to remember the happier times please help so i can help. This is how my best friend described her, please help me find a song that seems fitting to at least say something on a girl like this " ok kind sweet caring OCD loving bouncy full of life amazing she would always bounce off the walls and she would wake up at the weirdest times like 2:07 am was her favorite smart beyond all belief funny quirky and fun loving."
