Visitor-created playlist: Cheer-up songs

When I asked you what rain songs you enjoyed, not only did we create an extensive, large, and diverse list, but it became a place for people to discover new music. (If you haven't read and/or added to the "rain song" list, you can do that by clicking here.)

This is a cool thing we've got going, in my opinion, and I wanted to try it again...

We already learned how music can influence our emotions. And I'm sure that there are lots of people that have specific songs they listen to based on what mood they are in.

So, question: What songs do you listen to when you need to be cheered up?
