Does anyone have good inspirational song suggestions for a person overcoming depression?

My sister is suffering from extreme anxiety, depression, and PTSD. She attempted suicide and was submitted to a psych ward. She's now out, but is struggling to find her way in life. I feel like music can be a really great form of therapy, so I wanted to make her a CD or playlist of really good, inspirational songs that she might find some comfort in or be able to relate to. Any suggestions?
