I've recently come across the song "Life Happens" by Brandon and Leah. It's a really good pick-me-up or feel good song, and it helps remind you to always be happy, because no matter what things happen and you can't control it. The best way to deal with it is to look at the bright side and try not to let if affect you negatively. I like to listen to this song when I'm upset or not in the greatest mood. It also has a really happy beat, so it's hard to feel bad when you listen to it.
